Hello back,

18=(x+y)/3
18=(x-y)*3/5

==>(x+y)/3=(x-y)*3/5
==> 5(x+y)=9(x-y)
==>5x+5y=9x-9y
==>4x=14y
==>x=7/2y

18=(7/2y+y)/3
==>9/2*y=18*3
==>y=12
==> x=7/2*12=42
Sorry for the error.

Breaking the phrase down...

"The difference of Malik's height and 11" - this indicates subtraction.

m - 11

"is 44" - this indicates that the value of the diffrence would be '44'.

'= 44'

The equation should be:

m - 11 = 44

Hope this helps.

Help!! whats the answer? and how do I solve!! :(
Sever21 [200]
I think the answer is 20.25 because when solving for the area of a triangle you do 1/2 base times height and so the equation would be
1/2(9)(4.5)
you would start by doing 9(4.5) which equals 40.5
then you would divide by 1/2 which equals 20.25
hope this helps:)
