I need help urgently please

Answer 1

9s = 72

Explanation:

In total, there are 72 slices of pizza. They brought 9 pizzas. Since you need to find out how many slices each pizza has, you need to do inverse operations in order to solve the equation.

72/9 = 8 = s

Answer check:

9s = 72

9(8) = 72

So, each pizza has 8 slices.

Answer 2

You don't know how many slices are in a pizza but you do know how many there are all together so you have to divid the numbers that you know.
72/9=8 so there are 8 slices in 1 pie
