#14: mr. mcbride ordered 6 cheese pizzas and 7 pepperoni pizzas and
paid $153.50 for his son's birthday party. he realized he was going to
run out of pizza and made a second order. this time, he ordered 2
cheese and 2 pepperoni pizzas and paid $47.00. what is the cost of one
pepperoni pizza? *
your answer

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

50-60=10

step-by-step explanation:

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
