Step-by-step explanation:
let w = width
length = 3w-2
perimeter = 2*length + 2*width
perimeter = 2(3w-2) + 2w
perimeter = 6w - 4 + 2w
perimeter = 8w - 4
perimeter = 124 inch
8w - 4 = 124inch
<em>+4 to each side</em>
8w = 128inch
<em>divide each side by 8</em>
w = 16
length = 3w-2
= 3(16) - 2
length = 46 inch
Answer:
112.5 which is 113
Step-by-step explanation:
150 divided by 60= 2.5
2.5 times 45=112.5
The answer is 115 miles per hour
138,000/ 128,000 = 7.8125% Just divide new value into old value
The third one because each banner costs $16 and x is the number of banners, $32 is just a one time fee so there is no x.
