You told your friend that you could eat 9/12 of a large pizza. If you only ate 3/4 of what you said you could eat, what fraction of a large pizza did you eat?

9/16

Step-by-step explanation:

You need to find how much 3/4 is of 9/12.

If using a calculator ((3/4) * 9)/12 gives you a decimal of 0.5625 or 9/16

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

the aswere is the one with all 8's and the second one is with the 10,8 and 6
