The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
X-5 is your answer. hope that helps
If u think of it this way
8*4=32 it has to be smaller than that so my best guess would be
C) 20 square units
Answer:
(-2,2) (1,3)
Step-by-step explanation:
i got it on my test i just did.
12 inches in 1 foot
12*12*12 cubic inches in 1 cubic foot = 1728 in^2
So 7125 in^3 = 7125/1728 = 4.123 ft^3 to nearest thousandth
