a pizza shop charges $9 for a large cheese pizza. additional toppings cost $2 per topping. Heather paid $17 for her large pizza. how many toppings did she order. set up and equation and solve

Heather ordered 4 toppings.

Step-by-step explanation:

If the large pizza was 9$, and topping were 2$, than your equation should look like: 4x2 = 8 and 8+9 = 17

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
