Step-by-step explanation:

1. Total up the ratio

Ratio = 7

Total Balloon = 21

2.Divide Ratio with ttl balloons

21÷7 = 3

* so each box in the ratio is 3

Solid balloons = 4×3

= 12

Striped balloons = 3×3

=9

to confirm

12+9 = 21

Original ratio      Balloons at party

4                                      12

3                                      9

7                                      21

Step-by-step explanation:

1. The best thing you can do to start the problem is add the number of balloons in the original ratio to identify that there will be 7 in the original ratio.

2. Once we know that the total balloons ratio is 7 and know that the total balloons is 21 at the party, we can deduce that there is a 7:21 ratio which we can simplify to 1:3. To check just ask what 1 times 7 and 3 times 7 is.

3. Now that we know the original ratio for the total balloons we simply multiply solid balloons by 3 and striped balloons by 3.

4. 4x3=12, 3x3=9.

answer:   y=2x-3
