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)
On - 5 = 13; Alexa popped 18 balloons.
On + 5 = 13; Alexa popped 8 balloons.
On - 13 = 5; Alexa popped 18 balloons.
On - 5 =
13; Alexa popped 18 balloons.
The equation that can be used to determine the number of balloons Alexa popped is "On + 5 = 13", where "n" represents the number of balloons Alexa popped.
By rearranging the equation, we have "On = 13 - 5".
Substituting the values, "On = 8".
Therefore, Alexa popped 8 balloons.
The equation that can be used to determine the number of balloons Alexa popped is:
5 + n = 13
To solve for n (the number of balloons Alexa popped), we need to isolate the variable. Subtracting 5 from both sides of the equation gives us:
n = 13 - 5
Simplifying, we find:
n = 8
Therefore, Alexa popped 8 balloons. The correct equation and answer are:
5 + n = 13; Alexa popped 8 balloons.
To find the equation that can be used to determine the number of balloons Alexa popped, we can start by assigning variables. Let's say "K" represents the number of balloons Krista popped, and "A" represents the number of balloons Alexa popped.
According to the problem, Krista popped 5 balloons. So we can write that as:
K = 5
Together, they popped a total of 13 balloons. This means the sum of Krista and Alexa's balloons is equal to 13:
K + A = 13
Now, let's substitute the value of K (which is 5) into the equation:
5 + A = 13
Simplifying this equation, we subtract 5 from both sides:
A = 13 - 5
A = 8
So Alexa popped 8 balloons.
Therefore, the correct equation is:
K + A = 13
