What would be the equation for #23???
Rufina [12.5K]
Hi there!

Let r be the number of matches that Rebecca's team won.

We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.

Using this given information, we can create the following equation.

r+9=52

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

r=43

Have an awesome day! :)

Gina wants to take dance classes. She compares two dance studios to determine which has the best deal for her. Dance World charg
fomenos

Answer:

10 classes

Step-by-step explanation:

Given equations in the question

Dance World: y = 15x

Toe Tappers: y = 25 + 12.5x

Where,

x = number of classes

Equate the total cost at both dance studios

15x = 25 + 12.5x

Collect like terms

15x - 12.5x = 25

2.5x = 25

Divide both sides by 2.5

2.5x / 2.5 = 25 / 2.5

x = 10 classes

x = number of classes = 10
