Answer:
x/y=1/4
Step-by-step explanation:
3x+2y=3y-2
3x=3y-2y-2
3x=y-2
y=3x+2
x+y=10
x+3x+2=10
4x+2=10
4x=10-2
4x=8
x=8/4
x=2
2+y=10
y=10-2
y=8
x/y=2/8=1/4
Answer: My answer was wrong sorry
Step-by-step explanation:
Answer:
The height is 8 yds
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h where b1 and b2 are the lengths of the bases
108 = 1/2 ( 15+12) *h
108 = 1/2 ( 27)h
Multiply each side by 2
216 = 27h
Divide each side by 27
216/27 = 27h/27
8 =h
