First, find the area of the pool
(8)(4)(5) = 160
160 / 15 = 10.67
round 10.67 to 11
11(10) = 110
it will cost 110 dollars
Step-by-step explanation:
3x = 12 - 18
3x = (- 6)
X = (-6)/3
x = (-3)
Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x

Now that you have 11 = 4x you divide 4 on both sides 
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
Answer:
can you explain it more and then I will know the answer
Answer:
11 in
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Taking the square root of each side
sqrt(121) = sqrt(s^2)
11= s
