Krista and Alexa played balloon darts in a school fair. Krista popped 6 balloons, which is 1 balloon less than Alexa. Complete the working equation that represents the number of balloons, b , that Alexa popped and solve the equation.
Let b be the number of balloons that Alexa popped.
According to the given information, Krista popped 6 balloons, which is 1 balloon less than Alexa.
This can be expressed as: b - 1 = 6.
Adding 1 to both sides of the equation, we get b = 7.
Therefore, Alexa popped 7 balloons. Answer: \boxed{7}.
Let's assume that the number of balloons Alexa popped is represented by the variable "b".
We know that Krista popped 6 balloons, which is 1 balloon less than Alexa. This can be represented as:
Krista's balloons = Alexa's balloons - 1
So, the complete equation is:
6 = b - 1
To solve this equation, we need to isolate the variable "b". Adding 1 to both sides of the equation, we get:
6 + 1 = b - 1 + 1
Simplifying the equation, we have:
7 = b
Therefore, Alexa popped 7 balloons.
To create the equation, we need to represent the number of balloons that Alexa popped. We're given that Krista popped 6 balloons, which is 1 balloon less than Alexa. Therefore, if we let b represent the number of balloons that Alexa popped, the equation would be:
b = 6 + 1
Now, we can solve for the unknown variable b.
b = 6 + 1
b = 7
So, Alexa popped 7 balloons.
