Question

Responses

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

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

Answer 1

To find the number of balloons Alexa popped, we set up the equation based on the information given. Krista popped 5 balloons and together they popped 13 balloons, so we can write the equation as:

5 + n = 13

To isolate \( n \), we can rearrange the equation:

n = 13 - 5

By calculating, we find:

n = 8

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

n + 5 = 13; Alexa popped 8 balloons.

The correct response is:

n + 5 = 13; Alexa popped 8 balloons.
