3(x + 8) = 17....distribute the 3 thru the parenthesis 3x + 24 = 17...subtract 24 from both sides 3x = 17 - 24 3x = -7...divide both sides by 3 x = -7/3 or -2 1/3 <===
If 1 inch = 2.5 yards then x inch = 80 yards cross multiplying we have: 80 × 1 = x × 2.5 x = 80÷ 2.5 = 32 inches therefore the picnic area is 32 inches in the drawing.
