Comment on solving inequalities
These are the same steps you would use to solve the 2-step equation ...
... 3a -4 = 5
The only difference between solving equations and solving inequalities is that when you multiply or divide by a negative number, you reverse the sense of the comparison (> becomes <, and vice versa; ≥ becomes ≤, and vice versa). You can see this if you consider numbers: 2 > 1. Multiplying by -1 gives -2 < -1.
Abby buys 1 sheet of stickers. 5 strips of ten and 9 singles. How many stickers did she buy?
On the main street, the tourists walked for s km with a speed of v km/hour. On the side road, the tourists walked twice the distance that they covered on the main street. How much time t (in hours) did the tourists spend if it is known that on the side road they walked with a speed that was 2 km/hour less than their speed on the main road? Find t when s=10, v=6.
Answer:
6 2/3 hours
Step-by-step explanation:
We assume the time of interest is the total time spent on the main road and side road.
In each case, ...
... time = distance/speed
On the main road, ...
... tmain = s/v
On the side road, ...
... tside = (2s)/(v -2)
Then the total time spent is ...
... ttotal = tmain + tside
... = s/v + (2s)/(v -2)
For s=10 and v=6, this is ...
... ttotal = 10/6 + 2·10/(6 -2) = 5/3 + 20/4 = 5/3 + 5 . . . . hours
... ttotal = 6 2/3 hours

Step-by-step explanation:
A local garden club had 14 members with a mean age of 34. Then two new members joined. One was 24 years old, and the other was 36 years old. How did the mean age change after they joined? The mean age increased. The mean age decreased. It isn't possible to determine how the mean would change. The mean age stayed the same.
The mean age decreased.
Step-by-step explanation:I find it convenient to look at the additions with respect to the current mean age.
The current total age is 14×34. We have added members with ages (34 -10) and (34 +2), so the new total age is ...
... (34×14) + (34 -10) + (34 +2) = (16×34) - 8
Dividing this total by 16 will give the new mean age. (We already know it is less than 34.)
... ((16×34) -8)/16 = 34 - 1/2 = 33 1/2 . . . new mean age; a decrease

Math true or false
Septima investing money into two different accounts at the same time. the system of inequalities represent the balance of each account where x represents the number of years the money has been invested.
Math! Please help! Please explain your answers.
Answer:
FalseFalseTrueStep-by-step explanation:
Since the given expression represents the account balance, the initial amount (when x=0) is $500 in Account A, and $100 in Account B. (Less money was invested in account B.)
The growth rate of each account is $1.03 per year.* (The growth rate ($/year) is identical for each account.)
The total of the initial amounts invested is $500 +100 = $600.
_____
* Comment on growth rate
Since the account balance is shown as greater than or equal to the given expression, there appears to be the possibility that adjustments are made to the account balance by some means other than the growth predicted by this inequality. For example, if the balance in Account A is $900 at the end of 1 year, the inequality will still be true, but the extra $398.97 will be in addition to the $1.03 growth predicted by this expression.
This means we really cannot say what the growth rates of the accounts might be, except that it is a minimum of $1.03 per year in each account.
_____
Comment on the expressions
More usually, we would expect to see an account balance have the equation a = 400·1.03^x. That is, the interest rate would be 3% and it would be compounded annually. The expression 400 + 1.03x is very unusual in this situation.

Select Linear or Nonlinear for each function. Function Linear Nonlinear y=5x+1 y=23 y=1−2x2
The correct classification for each function is as follows:
1. [tex]\( y = 5x + 1 \)[/tex] - Linear
2. [tex]\( y = 23 \)[/tex] - Linear
3. [tex]\( y = 1 - 2x^2 \)[/tex]- Nonlinear
A linear function is one that can be written in the form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] and [tex]\( b \)[/tex] are constants, and [tex]\( x \)[/tex] is the independent variable. The graph of a linear function is a straight line.
1. For the function [tex]\( y = 5x + 1 \)[/tex], we can see that it is already in the form of a linear equation with [tex]\( m = 5 \)[/tex] and [tex]\( b = 1 \)[/tex]. Therefore, this function is linear.
2. The function [tex]\( y = 23 \)[/tex] is a constant function. Although it does not have an [tex]\( x \)[/tex] term, it can still be considered linear because it can be written as [tex]\( y = 0x + 23 \)[/tex], where the slope [tex]\( m = 0 \)[/tex] and the y-intercept [tex]\( b = 23 \)[/tex]. The graph of this function is a horizontal line, which is a special case of a linear function.
3. The function [tex]\( y = 1 - 2x^2 \)[/tex] contains an [tex]\( x^2 \)[/tex] term, which makes it a quadratic function. Quadratic functions are nonlinear because their graphs are parabolas, not straight lines. The presence of the [tex]\( x^2 \)[/tex] term means that the rate of change of [tex]\( y \)[/tex] with respect to [tex]\( x \)[/tex] is not constant, which is a key characteristic of nonlinear functions. Therefore, this function is nonlinear.

A rectangle has a length of 4 inches and a width of x inches. The value of the perimeter of the rectangle is equal to the value of the area of the rectangle. What is the value of x?
Final answer:
To find the value of x in a rectangle with a length of 4 inches, set up the equation 2(4 + x) = 4x and solve for x. The value of x is 4 inches.
Explanation:
To find the value of x, we need to set up an equation using the given information. The perimeter of a rectangle is equal to twice the length plus twice the width. The area of a rectangle is equal to the length times the width. So, we can set up the equation: 2(4 + x) = 4x. Next, solve the equation for x:
8 + 2x = 4x
8 = 4x - 2x
8 = 2x
4 = x
Therefore, the value of x is 4 inches.

Step-by-step explanation:
The total value of Ralph's stuff is ...
... 150 + 60 + 100 + 80 + 200 + 100 + 40 + 20 + 850 + 200 + 600 + 175 = 2575
The premium is 16.53% of that, so is ...
... 0.1653 × 2575 = 425.65
Answer:
The insurance company charges an annual premium of $425.65 .
Option (d) is correct .
Step-by-step explanation:
As given
Ralph wants to purchase a renters insurance policy for his new apartment.
His insurance company charges an annual premium of 16.53% of the approximate value of the items he owns and is keeping in his apartment.
Total amount of the items he owns and is keeping in his apartment = TV cost + VCR cost + DVD Player cost + Stereo cost + Sofa cost + Entertainment centre cost + Microwave cost + Coffee Maker cost + Computer cost + Bicycle cost + Coin Collection cost + Pictures/Posters cost
Putting all the values in the above
Total amount of the items he owns and is keeping in his apartment = $150 + $60 +$100 + $ 80 + $200 + $100 + $40 + $20 + $850 + $ 200 + $ 600 + $ 175
Total amount of the items he owns and is keeping in his apartment = $ 2575
16.53 % is written in the decimal form .
[tex]= \frac{16.53}{100}[/tex]
= 0.1653
Insurance company charges an annual premium = 0.1653 × Total amount of the items he owns and is keeping in his apartment .
= 0.1653 × 2575
= $ 425.65 (Approx)
Therefore the insurance company charges an annual premium of $425.65 .
Option (d) is correct .
Quinn is twice as old as karl and four years older than parker. The sum their ages is 21. How old is Parker
Answer:
Parker is 6 years old
Step-by-step explanation:
Parker is 6 years old
Step-by-step explanation:Let q, p, k represent the ages of Quinn, Parker, and Karl, respectively.
... q = 2k . . . . . . Quinn is twice as old as Karl
... q = p+4 . . . . . Quinn is 4 years older than parker
... q + p + k = 21 . . . . the sum of their ages is 21
_____
We can use the first two equations to find Karl's age in terms of Parker's.
... p+4 = q = 2k
... (p+4)/2 = k
Now, we can substitute for q and k in the last equation.
... (p+4) +p +(p+4)/2 = 21
... 5/2p +6 = 21 . . . . . . collect terms
... p = (2/5)(21 -6) . . . . subtract 6, multiply by 2/5
... p = 6 . . . . . . Parker is 6 years old
If GF is a midsegment of CDE, find CD.
A. 3.4
B. 6.8
C. 13.6
D. 14
Answer:
C
Step-by-step explanation:
Triangle CGF and triangle CED are similar. Hence, the ratio of their corresponding sides are equal. Thus we can write:
[tex]\frac{5x+4}{2x+3}=\frac{CD}{3x+0.8}[/tex]
We can now cross multiply and solve for CD:
[tex]\frac{5x+4}{2x+3}=\frac{CD}{3x+0.8}\\(5x+4)(3x+0.8)=(2x+3)(CD)\\15x^2+4x+12x+3.2=(2x+3)(CD)\\15x^2+16x+3.2=(2x+3)(CD)\\CD=\frac{15x^2+16x+3.2}{2x+3}[/tex]
Since GF is a midsegment of CDE, CD is double of CF. So we can write:
[tex]CD=2CF\\\frac{15x^2+16x+3.2}{2x+3}=2(3x+0.8)\\\frac{15x^2+16x+3.2}{2x+3}=6x+1.6\\15x^2+16x+3.2=(6x+1.6)(2x+3)\\15x^2+16x+3.2=12x^2+18x+3.2x+4.8\\15x^2+16x+3.2=12x^2+21.2x+4.8\\3x^2-5.2x-1.6=0[/tex]
By using quadratic formula [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex] and with a=3, b= -5.2, and c= -1.6, we find the value of x to be:
[tex]\frac{5.2+-\sqrt{(-5.2)^2-4(3)(-1.6)} }{2(3)}=2[/tex]
Since the expression for CD is [tex]\frac{15x^2+16x+3.2}{2x+3}[/tex] , we plug in [tex]x=2[/tex] into this expression to find value of CD:
[tex]\frac{15(2)^2+16(2)+3.2}{2(2)+3}=13.6[/tex]
The correct answer is C
Answer:
C. 13.6
Step-by-step explanation:
We have been given that GF is a mid-segment of CDE.
Since we know that mid-segment of a triangle is half the length of its parallel side.
We can see that ED is parallel to GF , so measure of GF will be half the measure of ED. We can represent this information as:
[tex]GF=\frac{1}{2}ED[/tex]
Let us substitute given value of GF and ED to find our x.
[tex]2x+3=\frac{1}{2}(5x+4)[/tex]
Multiply both sides of equation by 2.
[tex]2*(2x+3)=2*\frac{1}{2}(5x+4)[/tex]
[tex]2*(2x+3)=5x+4[/tex]
[tex]4x+6=5x+4[/tex]
[tex]6=5x+4-4x[/tex]
[tex]6=x+4[/tex]
[tex]6-4=x[/tex]
[tex]2=x[/tex]
We can see that triangle CFG is similar to triangle CDE, so we will use proportions to find length of CD.
[tex]\frac{CF}{GF}=\frac{CD}{ED}[/tex]
Substitute given values.
[tex]\frac{3x+0.8}{2x+3}=\frac{CD}{5x+4}[/tex]
Upon substituting x=2 in our equation we will get,
[tex]\frac{3*2+0.8}{2*2+3}=\frac{CD}{5*2+4}[/tex]
Let us simplify our equation.
[tex]\frac{6+0.8}{4+3}=\frac{CD}{10+4}[/tex]
[tex]\frac{6.8}{7}=\frac{CD}{14}[/tex]
[tex]14*\frac{6.8}{7}=CD[/tex]
[tex]2*6.8=CD[/tex]
[tex]13.6=CD[/tex]
Therefore, CD equals 13.6 and option C is the correct choice.
Barney works as a car salesman and earns $175 for every car that he sells. He has fixed expenses of $3100 every month. He has laid out his projected variable expenses as well as his projected car sales for the first 6 months of next year.
. EXPENSES VARIABLE CARS SOLD
january 2,600 32
feb 3,200 36
march 1,600 26
may 800 22
which month will barney sell enough cars to pay for all his monthly expenses ?
feb
Step-by-step explanation:When the number of cars needed to be sold to meet fixed plus variable expenses is subtracted from the number of cars projected to be sold, the result is negative for all months listed except February. In that month, Barney covers is expenses.
We have computed ...
... (expected car sales) - (needed car sales)
where ...
... (needed car sales) = (variable expenses + fixed expenses)/(income per car sold)
For January, this calculation gives ...
... 32 - (2600 +3100)/175 = 32 -32.571 = -0.571
That is, Barney does not project he will sell enough cars to pay his January expenses.
In February, the result is 0, which means he will sell enough cars in February to pay all his monthly expenses.
As a promotion, a clothing store draws the name of one of its customers each week. The prize is a coupon for the store. If the winner is not present at the drawing, he or she cannot claim the prize, and the amount of the coupon increases for the following week's drawing. The function f(x) = 20 (1.2)^x gives the amount of the coupon in dollars after x weeks of the prize going unclaimed. {{ x is the exponent on (1.2). }}
(A) What is the percent increase each week?
(B) What is the original amount of the coupon? (the initial value)
(C) What is the amount of the coupon after 2 weeks of the prize going unclaimed?
(D) After how many weeks of the prize going unclaimed will the amount of the coupon be greater than $100?
The given formula is f(x) = 20(1.2)^x
The formula is the starting amount multiplied by 1 + the percentage raised to the number of weeks.
A) the percent increase is 20% ( 1.2 in the formula is 1 +20% as a decimal)
B) the original amount is $20
C) for 2 weeks, replace x with 2 and solve:
20(1.2)^2
20(1.44) = $28.80
After 2 weeks the coupon is $28.80
D) To solve for the number of weeks (x) set the equation equal to $100:
100 = 20(1.2)^x
Divide both sides by 20:
5 = 1.2^x
Take the natural logarithm of both sides:
ln(5) = ln(1.2^x)
Use the logarithm rule to remove the exponent:
ln(5) = x ln(1.2)
Divide both sides by ln(1.2)
x = ln(5) / ln(1.2)
Divide:
X = 8.83
At 8.83 weeks the coupon would be $100, so after 9 weeks the coupon would be greater than $100
The answer is 9 weeks.

Which equation has the same solution as this equation? x^2-16x+12=0
Another equation that shares the same solutions as x²-16x+12=0 is 2x² - 32x + 24 = 0. This equation is the initial equation multiplied by 2 and thus would produce the same solutions when the quadratic formula is applied.
Explanation:The equation given is a quadratic equation, which is in the form ax²+bx+c = 0. The solutions of a quadratic equation are given by the formula: -b ± √b² - 4ac / 2a. This formula can be used to find the solutions of any other quadratic equation. For the given equation, x²-16x+12=0, the values of a, b, and c are 1, -16, and 12 respectively. So, another equation with the same solutions could be 2x² - 32x + 24 = 0. This equation has the same solutions because it's simply the initial equation multiplied by 2, so this doesn't change the results of the quadratic formula.

Eric is 6 1/6 feet tall and his brother is 5 3/4 feet tall. Eric is how many feet taller than his brother?
A. 1/5 feet
B. 5/12 feet
C. 7/12 feet
D. 3/4 feet
Answer:
B. 5/12 feet
Step-by-step explanation:
We know that Eric is [tex]6\frac{1}{6}[/tex] feet tall while his brother is [tex]5\frac{3}{4}[/tex] feet tall. We are supposed to find out how many feet is Eric taller than his brother.
So basically we have to find the difference between the height of the two brothers.
First, let's just change the mixed numbers to improper fractions:
[tex]6\frac{1}{6}[/tex] = [tex]\frac{37}{6}[/tex]
[tex]5\frac{3}{4}[/tex]= [tex]\frac{23}{4}[/tex]
Now taking their difference:
[tex]=\frac{37}{6} -\frac{23}{4}\\\\=\frac{148-138}{24}\\\\=\frac{10}{24}\\\\=\frac{5}{12}[/tex]
Therefore, Eric is 5/12 feet taller than his brother.
