Answer:
13.25 ft
Step-by-step explanation:
Let w represent the width of the window. Then w-5 represents the length, and the perimeter is ...
P = 2(L+W)
43 = 2((w-5) +w) = 4w -10
53/4 = w = 13.25 . . . feet
The width of the window is 13.25 ft.
12/10, 1.2, and any of the infinite multiples of the fraction such as 24/20, 120/100 etc...
2n + 28 = 96 [Two times n plus twenty-eight equals ninety-six.}
You need to get n by itself, so you first subtract 28 on both sides
2n + 28 - 28 = 96 - 28
2n = 68 Divide 2 on both sides
n = 34
All you have to do is divide 433.44 by the price of the hamburgers, so
433.44 ÷ 3.87 = 112
The answer is 112 (:
