Given

Solving (1): Amount of 18 cups

To do this, we calculate the amount of cups by the rate:

So, we have:

Solving (2): Amount of 183 cups

Solving (3): Amount of c cups

Solving (4): Number of cups for $127.50

To do this, we simply divide the amount by the rate

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
