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 18 balloons.
n minus 5 equals 13 ; Alexa popped 18 balloons.
n + 5 = 13; Alexa popped 8 balloons.
n + 5 = 13; Alexa popped 8 balloons.
The correct equation to determine the number of balloons Alexa popped is n + 5 = 13. To solve for n, we need to isolate the variable n.
First, subtract 5 from both sides of the equation: n + 5 - 5 = 13 - 5.
This simplifies to n = 8.
Therefore, Alexa popped 8 balloons.
So the correct answer is: n + 5 = 13; Alexa popped 8 balloons.
The correct equation to determine the number of balloons Alexa popped is: n + 5 = 13.
To find out how many balloons Alexa popped, we need to solve this equation.
n + 5 = 13
Subtracting 5 from both sides:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons.
So the correct answer is: n + 5 = 13; Alexa popped 8 balloons.
