To celebrate ratios, mrs. johnson’s class will make pizzas. julio is in charge of bringing in the sauce. there are 30 students in his class and each pizza serves 8. pizza sauce recipe pizzas pizza sauce 1 cup 2 3 4 which point should julio use to determine the amount of pizza sauce he needs to bring? a b c d

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
