Question

Krista and Alexa played balloon darts in a school fair. Krista popped 5 balloons and Alexa popped 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?(1 point)
Responses

n + 5 = 13
; Alexa popped 8 balloons.
n plus 5 equals 13 ; Alexa popped 8 balloons.

n − 5 = 13
; Alexa popped 18 balloons.
n minus 5 equals 13 ; Alexa popped 18 balloons.

n − 13 = 5
; Alexa popped 18 balloons.
n minus 13 equals 5 ; Alexa popped 18 balloons.

n + 13 = 5
; Alexa popped 8 balloons.

Answer 1

To find the equation that determines the number of balloons Alexa popped, we can start from the information given:

1. Krista popped 5 balloons.
2. Together, Krista and Alexa popped a total of 13 balloons.

We can express the total they popped with the equation:

\[ n + 5 = 13 \]

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

To solve for \( n \):

\[ n + 5 = 13 \]
Subtracting 5 from both sides:

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

Therefore, Alexa popped 8 balloons.

The correct response is:
**n + 5 = 13; Alexa popped 8 balloons.**
