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?
The equation that can be used to determine the number of balloons Alexa popped is 5 + n = 13. To solve for n, we need to subtract 5 from both sides of the equation.
n = 13 - 5
n = 8
Alexa popped 8 balloons.
Let's use the equation:
5 + n = 13
To find the number of balloons Alexa popped, we need to solve for n.
To simplify the equation, we subtract 5 from both sides:
n = 13 - 5
This gives us:
n = 8
So, Alexa popped a total of 8 balloons.
To determine the number of balloons Alexa popped, we can set up an equation based on the given information.
Let's call the number of balloons Alexa popped n.
According to the problem, Krista popped 5 balloons. So we have:
Krista's balloons = 5
Alexa's balloons = n
Together, they popped a total of 13 balloons, so we have:
Krista's balloons + Alexa's balloons = Total balloons
Substituting the given values, the equation becomes:
5 + n = 13
To calculate how many balloons Alexa popped, we can solve this equation by isolating the variable n.
Subtracting 5 from both sides:
n = 13 - 5
n = 8
Therefore, Alexa popped 8 balloons.
