Answer:
3 long sleeve ,5 t shirt
Step-by-step explanation:
4x+12y=56
x+y=8
multiply bottom equation by four
4x+12y=56
4x+4y=32
subtract the two equations
8y+24
divide both sides by eight
y=3
plug into original equation
x+3=8
simplify
x=5
Assuming equal on all sides, A = 1/2 t
1/2 t is <u>half</u> of t. That would mean A is half of T.
Because the Perimeter is all four sides of a 2 dimensional shape added up, whatever one side will be, the other sides will be the same too. So: I would say C.
3(y+1)+2y=8
3y + 3 +2y = 8
5y +3 = 8
-3 -3
5y = 5
