Answer:
$149.09
Step-by-step explanation:
56.75-14.10=42.65
42.65+41.50=84.15
84.15-11.03=73.12
73.12-7.25=65.87
65.87+83.22=149.09
The answer is -88
When you multiply and then divide
(a) need to find the number of books, we'll call it "b". then the money (6w) minus the cost of books (17b) equals change left over (w)
6w - 17b = w
6w - w = 17b
5w = 17b
(5/17)w = b
(b) if w = 34
(5/17) *34 = b
10 = b
Answer:
W = 15 ft. and L = 30 ft.
Step-by-step explanation:
Perimeter = 90 ft.
Twice as long as it is wide: L=2W
P = 2(L + W) = 2(2W + W) = 6W
90 = 6W
W = 15 ft. and L = 30 ft.
