ozzi

Answer:

\boxed{Side \ Length \ of \ hot \ tub = 4.8\ ft.}

What is the solution of the system?
damaskus [11]
3x +2y= 11 ----1
x -2 = -4y   ---- 2

Equation 2 times by 3
3x -6 = -12y

Subracting 2-1
3x-6=-12y
3x-11=-2y

Leaving 
5=-10y
y= -1/2

Hence 
B. is the solution

PS, If you rate this as "Brainiest" that would be most appreciated
