Answer:
7.5 feet on either side of the mirror
Explanation:
A mirror should be centered on a wall. The mirror is 36 inches wide and the wall is 18 feet wide. Which equation helps determine the distance x on each side of the mirror?
36 inches = 3 feet
so we are looking for the space remaining after hanging a a 3' mirror on a 18' wall:
x = 18'- 3'
space = 15'
The space on either side of the wall needs to be even so:
15'/2 = 7.5 feet on either side of the mirror
