Answer:
525%
Step-by-step explanation:
set 5 1/4 as a decimal.
5.25 then move decimal point two places to the right to get the percent
525%
Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
5x-14x=9-90
-9x=-81
9x=81
x=81/9
x=9
