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?(1 point) 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 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 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' by subtracting 5 from both sides of the equation. This gives us:
n + 5 - 5 = 13 - 5
n = 8
So, Alexa popped 8 balloons. Therefore, 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 solve this equation, we need to find the value of n, which represents the number of balloons Alexa popped.
n + 5 = 13
Subtract 5 from both sides of the equation:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons.
