Answer:

Susan is 5 years old

Step-by-step explanation:

Make a system of equations based on the info:

J=3S

M=J-5

J+M+S=30

Since we have the value of J, plug it in to either equation:

M=3S-5

Same deal with M:

3S+3S-5+S=30

7S-5=30

7S=35

S=5

So Susan is 5 years old

Answer:

a = -3

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.

Divide -8 from both sides:

(-8a)/-8 = (24)/-8

a = 24/-8

a = -3

a = -3 is your answer.

Answer:

a = -3 to find this answer divide both sides by -8

Answer:

152

Step-by-step explanation:

3(11)= 33

4(33+5)

4(33)=132

4(5)=20

132+20=152

The value of the expression 4(3x + 5) when x = 11 is 152. This was calculated by replacing x in the equation with 11, simplifying the resultant equation and finally calculating the product.

The student has asked to compute the value of 4(3x + 5) when x = 11. This a problem in the field of Algebra, where 'x' is a variable and the equation 4(3x + 5) is an expression.

First, let's substitute x in the equation with 11. So the equation becomes 4(3*11 + 5). Let's simplify the equation. This gives us 4(33 + 5), which equals 4*38. Multiplying 4 by 38 gives us the final answer, 152.

Answer: $661.50

Step-by-step explanation:

Taylor makes $771.25 per week and makes twice that much in two weeks.

2×771.25=2(700+70+1+0.25)=1400+140+2+0.50

So Taylor makes $1542.50 in two weeks.

Miley makes $440.50 per week and so will make $881 in two weeks. Since

1542.50−881=742.50−81=741.50−80=701.50−40=661.50

We know that Taylor will make $661.50 more than Miley in two weeks.

Hope this helps!

Adding two linear functions results in a linear function, which could be represented as '16 x - 12' or '17 x - 12'. Multiplying two linear functions results in a quadratic function, which could be represented as '72 x² - 204 x + 144'.

In this scenario, when the two linear functions are being combined by addition and multiplication, it results in an expression that could be either linear or quadratic. When you add two linear functions together: f(x) = ax + b and g(x) = cx + d, the result is also a linear function: h(x) = (a+c)x + (b+d). Therefore, both 16 x - 12 and 17 x - 12 could be the result of an addition of two linear functions.

However, when you multiply two linear functions, you get a quadratic function: i(x) = (ax + b)(cx + d) = acx^2 + (ad+bc)x + bd. So 72 x² - 204 x + 144 could be the result of a multiplication of two linear functions.

Given that the recursive formula for a sequence is [tex]a_n=a_{n-1}+2n[/tex]

The first term of the sequence is [tex]a_1=4[/tex]

We need to determine the first four terms of the sequence.

Second term:

The second term of the sequence can be determined by substituting n = 2 in the recursive formula.

Thus, we have;

[tex]a_2=a_{2-1}+2(2)[/tex]

[tex]a_2=a_{1}+2(2)[/tex]

[tex]a_2=4+4[/tex]

[tex]a_2=8[/tex]

Thus, the second term of the sequence is 8.

Third term:

The third term of the sequence can be determined by substituting n = 3 in the recursive formula.

Thus, we have;

[tex]a_3=a_{3-1}+2(3)[/tex]

[tex]a_3=a_{2}+2(3)[/tex]

[tex]a_3=8+6[/tex]

[tex]a_3=14[/tex]

Thus, the third term of the sequence is 14.

Fourth term:

The fourth term of the sequence can be determined by substituting n = 4 in the recursive formula.

Thus, we have;

[tex]a_4=a_{4-1}+2(4)[/tex]

[tex]a_4=a_{3}+2(4)[/tex]

[tex]a_4=14+8[/tex]

[tex]a_4=22[/tex]

Thus, the fourth term of the sequence is 22.

Hence, the first four terms of the sequence is 4, 8, 14, 22.

Anytime your adding a negative number, its the same as subtract a positive number.

Answer:

$22

Step-by-step explanation:

If she wants to own 26 necklaces. You take that number and subtract the four she already owns, leaving you with 22.

Answer:

She needs to spend $22.

Step-by-step explanation:

She has 4 necklaces. In order to have 26, she needs to buy more necklaces. How many does she need to buy?

We subtract 4 from 26.

26 - 4 = 22

She needs to buy 22 necklaces to have a total of 26 necklaces.

Each necklace costs $1.

22 necklaces cost 22 times $1.

22 * $1 = $22

Answer: She needs to spend $22.

24 hours

Step-by-step explanation:

1 hour

Painter1 1/40

Painter2 1/60

together 1/40+1/60=5/120=1/24

The time it would take them to paint a house working together is 24 hours.

More people to do a task means less time it will take.

Less people to do a task means more time it will take.

Thus, they are inversely related.

If x men take y time for a work,

We can define a constant as "Manpower" needed for doing that specific work.

Let we define:

Manpower needed for a work = y + y + y + .. + y = Time per man × count of men

Manpower needed for a work = xy

We are given that;

Time = 40hours

Time for her assistant= 60hours

Now,

First, let’s find their individual rates. The painter can paint 1/40 of a house per hour and the assistant can paint 1/60 of a house per hour. To find their combined rate, we add these fractions:

1/40 + 1/60 = 3/120 + 2/120 = 5/120

This means that together they can paint 5/120 of a house per hour. To find how long it would take them to paint one whole house (or 1/1), we use the formula:

Work done = Rate × Time 1/1 = (5/120) × Time Time

= (120/5) × (1/1) Time

= 24 hours

Therefore, by work and time the answer will be 24 hours.

The slope is -1/2 which is Option B

Step-by-step explanation:

A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal.

Example:  Find the line perpendicular to y = 3x

First, you flip the sign which makes 3 into -3

Next, you make the reciprocal which makes -3 into -1/3

Problem: Find the line perpendicular to y= 2x + 5

First, you flip the sign which makes 2 into -2

Next, you make the reciprocal which makes -2 into -1/2

Answer:  The slope is -1/2 which is Option B

The slope of a perpendicular line is the opposite reciprocal of the slope of the original line.

Opposite → -2

Reciprocal → -1/2

Therefore, the answer is -1/2

Answer:

340 degrees

Step-by-step explanation:

So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).

So the circumference of a circle = 2pi(r)

This means:

6 = 2pi(r)

Which means that

r = 6/2pi or r = 3/pi

Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:

Arc length is defined by: length = θr

Where θ is our angle value.

So lets plug in:

[tex]\frac{17}{3} = (angle)\frac{3}{\pi }[/tex]

Multiply by pi to get:

[tex]\frac{17\pi }{3} = 3(angle)[/tex]

Divide by 3 to get that:

θ = 17pi/9

So if we convert that from radians to degrees we get 340 degrees.
