Answer 1

To determine the number of balloons Alexa popped, we need to set up an equation based on the information given.

Krista popped 5 balloons, and together they popped a total of 13 balloons. So, we can create the equation:

\[ n + 5 = 13 \]

Where \( n \) is the number of balloons that Alexa popped.

To solve for \( n \):

1. Subtract 5 from both sides: \[ n = 13 - 5 \]
2. Which gives: \[ n = 8 \]

So, the equation that can be used to determine the number of balloons Alexa popped is:

\[ n + 5 = 13 \]

And Alexa popped 8 balloons.

Thus, the correct response is: n + 5 = 13; Alexa popped 8 balloons.
