Mandarinka [93]

Answer:

So Sara can fill 24 pint bottles completly with 3 gallons of juice.

Step-by-step explanation:

This question can be solved using a rule of three.

Each pint has 0.125 gallons. How many pints are 3 gallons?

1 pint - 0.125 gallons

x pints - 3 gallons

$0.125x = 3$

$x = \frac{3}{0.125}$

$x = 24$

So Sara can fill 24 pint bottles completly with 3 gallons of juice.

Answer:

Step-by-step explanation:

9(c+7)=27

9c+63=27 subtract 63 from both sides

9c= -36 divide by 9

c= -4

3(2r-8)+4r=76 foil

6r-24+4r=76 combine like terms

10r-24=76 add 24 to both sides

10r+100 divide by 10

r= 10
