Question

A mirror should be centered on a wall. The mirror is 4 feet wide and the wall is 20 feet wide. Which equation helps determine the distance x on each side of the mirror?

Answer 1

A). x + 4 + x = 20

Multiple-choices

A). x + 4 + x = 20

B). 4 + x + 4 = 20

C). x = 20 + 4 + 4

D). 4 = 20 + x + x

Step-by-step explanation:

The mirror will be in the middle of a wall which is 20 feet wide.

If the mirror is 4 feet, then 4 will be in the middle.

X will be on either side of the 4feet mirror.

Therefore:

x + 4 + x =20
