Krista and Alexa played balloon darts in a school fair. Krista popped 5 balloons and Alexa popped n
balloons. Together, they popped a total of 13 balloons. Which equation can be used to determine the number of balloons Alexa popped? How many balloons did she pop
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.
n minus 5 equals 13 ; Alexa popped 18 balloons.
The correct equation to determine the number of balloons Alexa popped is:
n + 5 = 13
To find the value of n, we need to isolate n on one side of the equation. We can do this by subtracting 5 from both sides:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons. So, the correct equation is:
n + 5 = 13 ; Alexa popped 8 balloons.
