<span><span>15 times 9.25 = 138.75 inches.
That leaves
144-138.75 = 5.25 inches for spaces.
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches
= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>

Answer:
2x + 3 = -7 ---> x = -5
4.5x - 7 = 20 ---> x = 6
-3x + 7 = 28 ---> x = -7
Step-by-step explanation:
2x + 3 = -7
2x = -10
x = -5
4.5x - 7 = 20
4.5x = 27
x = 6
-3x + 7 = 28
-3x = 21
x = -7
The answer A. 7 + 4 because it’s equal to 11 and 4-(-7) is 11
