There is a wall of 13 feet long and you want to hang three equally-sized travel posters of 2 feet width, on a wall so that the posters on the ends are each 1.75 feet from the end of the wall. You want the spacing between posters to be equal. Write and solve an equation to determine how much space you should leave between the posters.

Spacing between the posters will be 1.75 each

Step-by-step explanation:

We are given

The length of the wall = 13ft

width of the poster = 2ft ⇒2*3=6ft for three posters

Poster's from end of the wall = 1.75*2 = 3.50ft

let the spacing be = x ⇒ 2x for two spacing between three posters

Total length of the wall = 6 + 3.50 + 2x = 13

2x + 9.50 = 13

2x = 3.50

x = 1.75ft

So the spacing between the posters will be 1.75 each

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
