Which expression has a value that is equal to the given expression when n = 8? 2n + 10 A. 3n
B. 10n + 2
C. n² + 5
D. 2(n+5)

Answers

Answer:

D.

Step-by-step explanation:

2n + 10

When n = 8 we have

2*8 + 10

= 16 + 10

= 26.

When n = 8:

2(n + 5)

= 2(8 + 5)

= 2*13

= 26.

So it's D.

Answer:

D. 2(n+5)

−15x−40=23−8x
What does x =

Answers

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x  

Add 8x to both sides

-15x + 8x - 40 = 23

          -7x - 40 = 23

Add 40 to both sides

                - 7x = 23 + 40

                  -7x = 63

 Divide both sides by (-7)

            x = 63/-7

x = -9

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x

add 8x to both sides to bring -8x to the left side

-15x + 8x - 40 = 23

add 40 to both sides to bring -40 to the right side

-15x + 8x = 23 + 40

add the common terms

-7x = 63

for x to be alone divide -7 to both sides

x = -9

What value of w makes the equation 145 = w + 27 true?

Answers

Answer:

118

Step-by-step explanation:

In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.

Answer:

118

Step-by-step explanation:

145 = w + 27

Switch the + sign before the 27 and switch into a minus and move it to the other side.

145-27=w

145-27=118

w=118

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units

Answers

Answer: a) The figure can be reasonably divided into two geometries:

• a rectangular prism

• a hemisphere.

b) The volume of the rectangular prism is given by

  V = lwh

  V = (10 cm)(5 cm)(4 cm) = 200 cm³

The volume of the hemisphere is given by

  V = (2π/3)r³

  V = (2π/3)(3 cm)³ = 18π cm³

c) The total volume of the figure is

  total volume = (prism volume) + (hemisphere volume)

  V = 200 cm³ + 18π cm³

  V ≈ 256.549 cm³

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.

Write an expression to model this situation.
How far could you travel if you drove 40 miles?

Answers

Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)

Step-by-step explanation:

The equation for these types of problems is y = mx + b.

M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.

Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.

If you plug everything in, you would get y= $0.20x + $35.

I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.

Now that we know x would be the amount of miles, we can plug that into the equation.

You would get y= $0.20 * 40 + $35.

Sorry, I’m not that good at explaining, but I hoped this helped!

y= .20x + 35

It would cost $43 to travel 40 miles

A line passes through the points (1, 4) and (3, –4). Which is the equation of the line?

Answers

y = -4x + 8

First you need to find the slope of the line.

The slope formula is m = y2-y1/x2-x1

If you plugged in the points it would be m = -4-4/3-1

so m = -8/2 = -4

so the slope is -4

now we need to write the equation of the line

for this u use point slope form

the formula for that is y-y2=m(x-x1)

so if you plug it in it would be:

y-(-4)=-4(x-3)

now you solve

y+4=-4x+12

y+4-4= -4x+12-4

y = -4x + 8

and now you have the slope of the line
