We can sum two fractions if they have the same denominator, so we have to rewrite both fractions so that they'll have the same denominator.
We can generate equivalent fractions by multiplying both numerator and denominator by the same number.
So, we have
[tex]-\dfrac{7}{9} = -\dfrac{7\cdot 10}{9\cdot 10} = -\dfrac{70}{90}[/tex]
Similarly, we have
[tex]-\dfrac{5}{10} = -\dfrac{5\cdot 9}{10\cdot 9} = -\dfrac{45}{90}[/tex]
Now we can sum the fractions:
[tex]-\dfrac{7}{9}-\dfrac{5}{10} = -\dfrac{70}{90}-\dfrac{45}{90} = \dfrac{-70-45}{90} = -\dfrac{115}{90} = -\dfrac{23}{18}[/tex]
To simplify the expression -7/9 - 5/10, find a common denominator, which is 90, convert and add the fractions to get -115/90, which is the simplified form of the expression.
The question asks to simplify the expression -7/9 - 5/10. To do this, we need to find a common denominator to combine these fractions. The least common denominator (LCD) for 9 and 10 is 90.
First, convert both fractions:
-7/9 = (-7*10)/(9*10) = -70/90-5/10 = (-5*9)/(10*9) = -45/90Then, add the fractions:
-70/90 - 45/90 = -115/90
Finally, it is usually a good practice to simplify the fraction, but in this case, -115 and 90 do not have any common factors other than 1, so the simplified expression is -115/90.

Two lines, A and B, are represented by the equations given below:
Line A: y = x – 6
Line B: y = 3x + 4
Which of the following shows the solution to the system of equations and explains why?
(–5, –11), because the point satisfies both equations
(–5, –11), because the point does not lie on any axis
(–3, –5), because the point satisfies one of the equations
(–3, –5), because the point lies between the two axes
ANSWER
(–5, –11), because the point satisfies both equations
EXPLANATION
The given equations are:
Line A: y = x – 6
Line B: y = 3x + 4
We substitute (-5,-11) into both equations.
Line A: -11 = -5– 6
This implies that,
-11=-11
This statement is true.
Line B: -11= 3(-5)+ 4
-11= -15+ 4
-11=-11
This is also true.
Since this point ,(&6,-11) satisfy both equations, it is their solution.

what is the value of s4
ANSWER
[tex]S_4 = \frac{208}{375} [/tex]
EXPLANATION
The given series is:
[tex]\sum_{n=1}^{\infty} \frac{2}{3} ( - { \frac{1}{5} })^{n - 1} [/tex]
When n=1, the first term is
[tex]a = \frac{2}{3} [/tex]
The sum of terms of a geometric sequence is given by the formula;
[tex]S_n = \frac{a {(1 - {r}^{n} )} }{1 - r} [/tex]
The sum of the first 4 terms is:
[tex]S_4= \frac{ \frac{2}{3} {(1 - { ( - \frac{1}{5} )}^{4} )} }{1 - - \frac{1}{5} } [/tex]
[tex]S_4 = \frac{208}{375} [/tex]
The value for S4 is represented by the third option, [tex]\frac{208}{375}[/tex] .
Geometric SequencesYou can define a geometric sequence when you have a common ratio between the numbers of a sequence. This common ratio can be found when you multiply or divide the previous term by the next term of the sequence and you find the same value. The formula for geometric sequences is:
[tex]a_n=a_1*r^{n-1}[/tex], where:
[tex]a_n[/tex]=[tex]n^{th}[/tex] term
[tex]a_1[/tex]= the first term
Example
2, 4,8, 16, ....
Here, you have:
[tex]a_1[/tex]= 2
[tex]r=\frac{a_2}{a_1}=\frac{a_3}{a_2}=2[/tex] , then: 2 x 2= 4; 4 x 2=8; 8 x 2=16 - Note that the numbers represent the example sequence.
For solving this exercise also it is necessary to apply the formula for the geometric sequence for finite terms since the question asks [tex]S_4[/tex], in the other words, the sum for n=4. Thus,[tex]S_n=\frac{a_1*(1-r^n)}{1-r}[/tex].
For the given series, when n=4, you have
[tex]\frac{2}{3} *(\frac{-1}{5})^{n-4} \\ \\ \frac{2}{3} *(\frac{-1}{5})^{4-4}\\ \\ \frac{2}{3} *(\frac{-1}{5})^{0}\\ \\ \frac{2}{3} *1=\frac{2}{3}[/tex]
Therefore, [tex]a_1=\frac{2}{3}[/tex].
Now, you will find S4 from the formula for the geometric sequence for finite terms
[tex]S_n=\frac{a_1*(1-r^n)}{1-r}\\ \\ =\frac{\frac{2}{3}\cdot \left(1-\left(-\frac{1}{5}\right)^4\right)}{1-\left(-\frac{1}{5}\right)}\\ \\ \frac{\frac{2}{3}\left(1-\left(-\frac{1}{5}\right)^4\right)}{1+\frac{1}{5}}=\frac{\frac{416}{625}}{\frac{6}{5}}=\frac{416\cdot \:5}{625\cdot \:6}=\frac{208}{375}[/tex]

3/4 times what equals 1/4
Final answer:
To find what multiplied by 3/4 equals 1/4, set up the equation 3/4 * x = 1/4 and solve for x, giving the answer x = 1/3.
Explanation:
This question demands basic understanding of multiplication and reciprocals.
The question asks, "3/4 times what equals 1/4?". To find the answer, we can set up the equation 3/4 * x = 1/4, where x is the unknown we are trying to find. Solving for x involves dividing both sides of the equation by 3/4 to isolate x.
Therefore, the equation simplifies to x = (1/4) / (3/4). Performing the division gives us x = 1/3. This means that 1/3 is the number you need to multiply by 3/4 to get 1/4.
To find what number multiplied by 3/4 equals 1/4, divide 1/4 by 3/4, which is the same as 1/4 times the reciprocal of 3/4 (4/3), resulting in 1/3.
To find out 3/4 times what equals 1/4, we are essentially looking for a number that when multiplied by 3/4 gives us 1/4. The mathematical operation we need to use is division since we want to find what 1/4 divided by 3/4 is. So, the equation we are solving is (1/4) ÷ (3/4).
When we divide fractions, we multiply by the reciprocal of the divisor. The reciprocal of 3/4 is 4/3. So, the calculation now is (1/4) × (4/3).
Multiplying the numerators and denominators separately, we get (1 × 4) / (4 × 3) which simplifies to 4/12. After simplification, 4/12 reduces to 1/3. Therefore, 3/4 times 1/3 equals 1/4.
Complete question is :
3/4 times is what equals 1/4?
A university conducted a study and determined that a college student walks an average of 2.4 miles a day and a college graduate walks an average of 1.8 miles per day. Which of the following is the best way to represent this data? -using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8 -using a cube with a side length of 2.4 and a cube with a side length of 1.8 -using a pie chart with one section labeled 1.8 and one section label 2.4 -using a square with a side length of 2.4 and a square with a side length of 1.8
Answer:
Using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8
Step-by-step explanation:
You use a bar graph to compare things between different groups, so it is the most appropriate one to use.
You use a pie chart to compare parts of a whole, so it would not be appropriate.
The graph should represent the relative sizes of the two values (24:18 or 1.33:1). Using a square or a cube would distort the relationship. The relative area of the squares would be 1.77:1 and that of the cubes would be 2.37:1.
Charts are used to represent data graphically.
The best way to represent the data is (a) using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8
The given parameters are:
[tex]\mathbf{Student = 2.4}[/tex]
[tex]\mathbf{Graduate = 1.8}[/tex]
Both data elements, are for different people.
So, it is best to use a bar chart.
Using a pie chart will imply that, the data elements are part of a whole data for a particular person.
Squares and cubes cannot be used at all.
Hence, the correct option is (a).

If line s and line t are parallel lines cut by transversal line r, what is the value of x?
x = 18
x cannot be determined from the information given
x = 33
x = 12
Answer:
Because s and t are parallel x=12
Step-by-step explanation:
To get this you have to solve for (4x-12)+120=180 solve for x
4x+12=60
4x=48
=12
The equation is written as 4x - 12 + 120 = 180. Then the value of the variable 'x' will be 18. Then the correct option is A.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The sum of the angle (4x - 12)° and (120)° will be equal to 180°. Then the equation is given as,
4x - 12 + 120 = 180
Simplify the equation, then we have
4x - 12 + 120 = 180
4x = 72
x = 72 / 4
x = 18
The equation is written as 4x - 12 + 120 = 180. Then the value of the variable 'x' will be 18. Then the correct option is A.

Answer:
The mass of the pipe is [tex]465\ g[/tex]
Step-by-step explanation:
step 1
Find the volume of the steel pipe
The volume is equal to the area of outside circle minus the area of inside circle, multiplied by the length of the pipe
so
[tex]V=\pi [r2^{2}-r1^{2}]L[/tex]

The Kwans are saving for their daughter’s college education. If they deposit $12,000 in an account bearing 6.4% interest compounded continuously, how much will be in the account when Ann goes to college in 12 years? a. $12,768 c. $21,216.12 b. $25,865.41 d. $76,800
After 12 years there will be $25,865.41 in the bank account when Ann goes to college option (b) is correct.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
The formula for the compounded continuously:
[tex]\rm A = Pe^{rt}[/tex]
r = 6.4% = 0.064
t = 12
P = $12,0000
[tex]\rm A = 12,0000e^{0.064\times12}[/tex]
After solving:
A = $25,865.41
Thus, after 12 years there will be $25,865.41 in the bank account when Ann goes to college option (b) is correct.

Please help me with this. TWO LINES MEET AT A POINT THAT IS ALSO THE ENDPOINT OF TWO RAY'S. SET UP AND SOLVE THE APPROPRIATE EQUATIONS FOR m AND N.
Answer:
m=47, n=52
Step-by-step explanation:
m is equal to 90-43 since 43+m is a right angle (straight angle 180 is composed of two right angles). n is equal to 90-38. If you solve of the missing angle not given a variable, you find n as well because opposite angles are congruent and have the same measure.
the map shows Hope road and the construction site for the new library find the equation of a street that passes through the building site and is parallel to the Hope road
Answer: y=1/3x+4
You're welcome
Answer: [tex]x-3y+12.5=0[/tex]
Step-by-step explanation:
From the give en graph , the coordinates of the point marked for library =(7,6.5)
The slope of the Hope road passing from points (0,6) and (3,7) is given by :-
[tex]\text{Slope}=\dfrac{\text{Change in y-coordinate}}{\text{Change in x-coordinate}}\\\\\Rightarrow\ \text{Slope}=\dfrac{7-6}{3-0}=\dfrac{1}{3}[/tex]
Since , a street that passes through the building site and is parallel to the Hope road, then the slope of the street will be :-
[tex]m=\dfrac{1}{3}[/tex]
[ The two parallel sides have same slopes. ]
Now, the equation of line having slope [tex]m=\dfrac{1}{3}[/tex] and passing through (7,6.5) is given by :-
[tex](y-6.5)=\dfrac{1}{3}(x-7)\\\\\Rightarrow3(y-6.5)=x-7\\\\\Rightarrow\ 3y-19.5=x-7\\\\\Rightarrow x-3y+12.5=0[/tex]
Hence, the equation of a street that passes through the building site and is parallel to the Hope road : [tex]x-3y+12.5=0[/tex]
A real estate agent received a 6% commission on the selling price of a house. If his commission was $8,880, what was the selling price of the house?
Answer:
6% x = 8,880 : x = selling price of house.
x = $148,000 : solve for x
Step-by-step explanation:
The selling price of the house can be calculated by dividing the commission ($8,880) by the commission rate (0.06). This gives a selling price of $148,000.
Explanation:To solve this problem, you need to understand that the 6% commission the real estate agent received is based on the selling price of the house. You can find the selling price by dividing the commission by the percentage commission expressed as a decimal.
Here's the step-by-step solution:
Convert the 6% commission rate to a decimal by dividing 6 by 100, which gives 0.06.Next, divide the commission amount ($8,880) by the commission rate (0.06). Using this calculation, $8,880 / 0.06, we find that the selling price of the house is $148,000.So, the selling price of the house on which the agent earned an $8,880 commission at a rate of 6% was $148,000.

If point A is located at (-7,5) and is rotated around 270 clockwise about the origin, then point A' is located at...
a. (5,7)
b. (-5,-7)
c. (5,7)
d. (7,5)
e. (-7,-5)
Answer:
B.(-5,-7)
Step-by-step explanation:
According to the rule of rotation if you were to have a 270* clockwise you would first switch the x and y values. Ex: (-7,5) -> (5,-7). next you would make the original y coordinate a negative. (5,-7) -> (-5,-7).
