A rectangle has a length that is 8 less than its width, w. The perimeter is 52. Which equation can be used to determine its
width?
8-W-52
2(w-8) +2w=52
(W-8)+W=52
2(8-W) +2w=52

2(w-8) +2w=52

its perimeter so u multiply everything by 2 and since u dont know the length but know its 8 less u subtract by width

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
