80 cups
1 qal X 4 qts x2pts x2 cups= 16 cups in one gallon
16x5=80
-9-(12-3x)=-9-1*(12)-1*(-3)=-9-12+3x=-21+3x=3(x-7)
-- Both pairs of sides of a rectangle are parallel.
Only one pair of sides of a trapezoid are.
-- A rectangle is a parallelogram.
A trapezoid isn't.
-- The opposite sides of a rectangle are equal.
The opposite sides of a trapezoid aren't.

The area of a trapezoid is (height) times (the average of the two bases).
Answer:
Step-by-step explanation:
x= 180-110(angles on a straight line)
x= 70
y=x=70 (alternate angles)
z= 110(alternate angles)
