Answer:
z+150=180
z=30
then again
x+x+20+30=180
2x=180-50
2x=130
x=130/2
x=65
Step-by-step explanation:
x
31 cups because 38 cups fit into 9 1/2 quarts so subtract 7 from 38 you get 31
7/15 / (3/5)
Flip the 2nd fraction and multiply:

Multiply the numerators and denominators together:
35/45
Divide 5 to the numerator and denominator:
35 / 5 = 7
45 / 5 = 9
7/9
