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. (1 point)
b = 6 + 1
b = 7
The equation is b = 7.
Let's work through the problem step by step:
Step 1: Define the unknown variable.
Let's assume the number of balloons that Alexa popped is "b".
Step 2: Set up the equation.
We know that Krista popped 6 balloons, which is 1 less than Alexa. So, the equation can be set up as:
b - 1 = 6
Step 3: Solve the equation.
To solve the equation, we can isolate the variable "b" by adding 1 to both sides:
b - 1 + 1 = 6 + 1
b = 7
Therefore, the number of balloons that Alexa popped, represented by "b", is 7.
Let's represent the number of balloons that Alexa popped as "x".
According to the information given, we know that Krista popped 1 balloon less than Alexa. So, we can write an equation:
Krista's balloons = Alexa's balloons - 1
6 = x - 1
To solve this equation and find the value of x, we can add 1 to both sides of the equation:
6 + 1 = x - 1 + 1
7 = x
Therefore, Alexa popped 7 balloons.
