Question

Responses

n − 5 = 13; Alexa popped 18 balloons.

n − 13 = 5; Alexa popped 18 balloons.

n + 5 = 13; Alexa popped 8 balloons.

n + 13 = 5; Alexa popped 8 balloons.

Answer 1

The equation that can be used to determine the number of balloons Alexa popped is: n + 5 = 13.

To solve this equation, we need to isolate the variable 'n':

n + 5 - 5 = 13 - 5

n = 8

Therefore, Alexa popped 8 balloons.

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