Mrs Gutierrez ordered 1 cheese pizza, 1 pepperoni pizza, and 1 sausage pizza. Each pizza is cut into 12 pieces. The students are 10/12 of the cheese pizza, 9/12 of the pepperoni pizza, and 3/12 of the sausage pizza. What fraction of all the pizza is left?

1 whole or 12/12

Step-by-step explanation:

so you go and subtract and you ad what each one equals

                                       10-12=2

                                         9-12=3

                                         3-12=9

                                      =  1 whole OR 12/12

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
