Krista and Alexa played balloon darts in a school fair. Krista popped 5 balloons and Alexa pooped n balloons together they pooped 5 balloons and Alexa n balloons. together they popped a total of 13 balloons which equation can be used to determine the number of balloons Alexa popped how many balloons did she pop?

Question

n + 5 = 13

n - 13 = 5

n - 5 = 13

n + 13 = 5

Answer 1

To find the correct equation to determine the number of balloons Alexa popped, let's clarify the situation:

• Krista popped 5 balloons.
• Alexa popped \( n \) balloons.
• Together they popped a total of 13 balloons.

So we can create the equation:

\[ n + 5 = 13 \]

This is the equation that represents the scenario correctly because the sum of the balloons they both popped equals 13.

Now, solving for \( n \):

\[ n + 5 = 13 \ n = 13 - 5 \ n = 8 \]

So, Alexa popped 8 balloons.
