Step-by-step explanation:
Students 8 x
Time taken (hours) 18 18 - 12 = 6

Answer:
X=3
Step-by-step explanation:
No matter how many pizzas he orders (P) he will be charged 4.50. then each pizza is worth 9.50 so you multiply that by how many he orders (5)
c=4.5+9.5p
c=4.5+9.5(5)
c=$52
for these problems you do the opposite of what is shown
1. h+7=15, subtract 7 from each side. h=8
2. m-10=24, add 10 to each side m=34
3.6t=96, divide both sides by 6 t=16
4. multiply both sides by 7, p=21.
