Sasha is ordering balloons for a party. She wants to have a red and blue balloons with a ratio of 6 red to 10 blue. If she wants to purchase 300 balloons total, how many red balloons will she need to
purchase?

112.5 Red balloons

Step-by-step explanation:

6:10

We can set up a proportion to solve

6/6+10=6/16

6/16=x/300

16x=300*6

16x=1800

x=112.5

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
