Question

Responses

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

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

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

n − 5 = 13; Alexa popped 18 balloons.

Answer 1

To find the number of balloons Alexa popped, we start with the information given:

Krista popped 5 balloons, and together they popped a total of 13 balloons.

We can set up the equation:

\[ 5 + n = 13 \]

where \( n \) represents the number of balloons Alexa popped.

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

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

So, the correct equation is:

\[ n + 5 = 13 \]

And Alexa popped 8 balloons.

Thus, the response is:

n + 5 = 13; Alexa popped 8 balloons.
