n − 13 = 5; Alexa popped 18 balloons.
n minus 13 equals 5 ; Alexa popped 18 balloons.
n − 5 = 13; Alexa popped 18 balloons.
n minus 5 equals 13 ; 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.
To determine the number of balloons Alexa popped, we can set up an equation where the number of balloons Krista popped (5) plus the number of balloons Alexa popped (n) equals the total number of balloons popped (13).
Therefore, the correct equation is:
n + 5 = 13
To find the value of n, we subtract 5 from both sides of the equation:
n + 5 - 5 = 13 - 5
n = 8
So Alexa popped 8 balloons. The correct statement is:
n + 5 = 13; Alexa popped 8 balloons.
