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 − 1 =
b =
balloons
b - 1 = 6
b = 7 balloons
The working equation that represents the number of balloons, b, that Alexa popped is:
b - 1 = 6
To solve the equation, we need to isolate the variable b.
Adding 1 to both sides of the equation:
b - 1 + 1 = 6 + 1
b = 7
Therefore, Alexa popped 7 balloons.
To find the number of balloons that Alexa popped, we can set up the equation "b - 1 = 6" where "b" represents the number of balloons Alexa popped and 6 is the number of balloons Krista popped.
To solve this equation, we need to isolate "b" on one side of the equation. To do this, we can add 1 to both sides of the equation:
b - 1 + 1 = 6 + 1
b = 7
Therefore, Alexa popped 7 balloons.
