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
Let's assume that the number of balloons Alexa popped is represented by "x".
We know that Krista popped 5 balloons, so the total number of balloons they popped together is 5 + x.
According to the problem, they popped a total of 13 balloons, so we can set up the equation:
5 + x = 13
Now, solve for x:
x = 13 - 5
x = 8
Therefore, Alexa popped 8 balloons.
