Step-by-step explanation:

3q - 2 - q = -18

3q - q = -18 + 2

2q = -16

q = (-16)/2

q = -8 → Proved

If l=3, w= 3, and h= 5, what is the volume of this box​
ArbitrLikvidat [17]

Answer and Step-by-step explanation:

To find the volume, we multiply the length by the width by the height for a rectangular prism (aka the box).

length = l = 3

width = w = 3

height = h = 5

Now, we multiply each together.

3 × 3 × 5

9 × 5

45

<u>The volume of the box is 45.</u>

Find the measure of angle ABC.<br><br> A. 124<br><br> B. 97<br><br> C. 56<br><br> D. 51
Airida [17]

Answer: Last Option

Step-by-step explanation:

By definition the sum of the internal angles of a triangle must always be equal to 180 °.

This means that:

32 + (2x-15) + (x-5)=180

Now we solve the equation for the variable x

32 + 2x-15 + x-5=180

2x+x +32-15-5=180

3x +32-20=180

3x +12=180

We subtract 12 in both barks of the equation

3x +12-12=180-12

3x=168

Divide by 3 on both sides of the equation

\frac{3}{3}x=\frac{168}{3}

x=\frac{168}{3}

x=56

Finally the measure of angle ABC is: (56-5)° = 51°

What is the midpoint of (8,10) and (-8,8)
nasty-shy [4]

9514 1404 393

Answer:

  (0, 9)

Step-by-step explanation:

The midpoint coordinates are the averages of the end point coordinates.

  M = (A +B)/2

  M = ((8, 10) +(-8, 8))/2 = (8 -8, 10+8)/2 = (0, 18)/2

  M = (0, 9)

The midpoint is (0, 9).
