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.
The equation that represents the number of balloons that Alexa popped is: b - 1 = 6.
Solving the equation, we add 1 to both sides: b = 6 + 1.
Therefore, Alexa popped a total of 7 balloons. Answer: \boxed{7}.
Let's represent the number of balloons that Alexa popped as "x".
According to the problem, Krista popped 1 balloon less than Alexa, so we can say:
Krista's balloons = Alexa's balloons - 1
Substituting the values we know:
6 = x - 1
To solve for x, we need to isolate it on one side of the equation. Adding 1 to both sides:
6 + 1 = x - 1 + 1
7 = x
Therefore, Alexa popped 7 balloons.
To complete the working equation, we know that Krista popped 6 balloons, which is 1 balloon less than Alexa. So, let's assume Alexa popped "x" balloons.
Therefore, the equation representing the number of balloons Alexa popped would be:
x = 6 + 1
Now we can solve the equation to find the value of x:
x = 6 + 1
x = 7
So, Alexa popped 7 balloons.
