A rectangular garden is 44 feet longer than it is wide. it's perimeter is 328 feet. What s this equation?
1 answer:
Suppose width is X
then length would be X+44
perimeter of rectangle = 2 (length + width)
substitute:
328 = 2 ( X+44 + X )
328 = 2 ( 2X + 44 )
328 = 4X + 88
328 - 88 = 4X
240 = 4X
240/4 = X
X = 60
substitute in the first and second line
width is X so width = 60 feet
length is X + 44 = 60 + 44 = 104 feet

So first you would substitute j and k in the expression.
7(0.5)+5-8(0.25)
3.5+5-2
It would equal 6.5
Hope this helps!
yes I know but will not give answer because you have not say that
2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
