Answer:
simplify: 2.5 =(y+5)
reorder the terms: 2.5y=(5+y)
remove the parenthesis: 2.5y=5+y
solving: 2.5y=5+y
move all terms containing y to the left, all other terms to the right.
add -1y to each side of the equation
2.5y+-1y=5+y+-1y
combine like terms 2.5y+-1y=1.5y
1.5y=5+y+-1y
combine like terms: y+-1y=0
1.5y=5+0
1.5y=5
divide each side by 1.5
y=3.333333333
simplifying
y=3.333333333
Step-by-step explanation:
Perimeter of a rectangle is
2*width + 2*length
then multiply the perimeter by the cost per foot
2*(150ft) + 2*(200ft)
300ft + 400ft
700ft
700ft * $10/ft
$7000
