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 + 5 = 13; Alexa popped 8 balloons.
n − 5 = 13; Alexa popped 18 balloons.
n − 13 = 5; Alexa popped 18 balloons
n + 13 = 5; Alexa popped 8 balloons.
The correct equation is n + 5 = 13. By subtracting 5 from both sides, we can determine that n = 8. Therefore, Alexa popped 8 balloons.
The correct equation is n + 5 = 13, which means that the number of balloons Alexa popped plus the 5 balloons that Krista popped equals the total of 13 balloons. To find out how many balloons Alexa popped, we can subtract 5 from both sides of the equation: n = 13 - 5. This simplifies to n = 8. Therefore, Alexa popped 8 balloons.
So, the correct answer is:
n + 5 = 13; Alexa popped 8 balloons.
To determine the equation that can be used to determine the number of balloons Alexa popped, we need to analyze the information given.
We know that Krista popped 5 balloons and Alexa popped n balloons. Together, they popped a total of 13 balloons.
This can be represented by the equation n + 5 = 13, where n represents the number of balloons Alexa popped.
To find the value of n, we can isolate it by subtracting 5 from both sides of the equation:
n + 5 - 5 = 13 - 5
n = 8
Therefore, the equation that can be used to determine the number of balloons Alexa popped is n + 5 = 13, and Alexa popped 8 balloons.
So, the correct answer is: n + 5 = 13; Alexa popped 8 balloons.
