X+y=17 solve for a variable and plug into the 2nd equation
(x+3)/y=1 also could be written as x+3=y
x=17-y
17-y+3=y combine and add y over to other side
20=2y
y=10
plug back in x+10=17
x=7
so the original fraction is 7/10
Wouldnt it be 4 im pretty sure i did the math right i hope this works can you answer mine?
10x+2y, this is the simplified version
Answer:
Step-by-step explanation:
volume of a cylinder=πr^2*h
226.2=3.14*8*r^2
226.2=25.12*r^2
226.2/25.12=r^2
9=r^2
=r
3=r
radius =3 feet
