Question

Alex played basketball 20 minutes longer on Tuesday than she did on Monday. She played for a total of 110 minutes for both days. Which equation can be used to find the number of minutes Alex played on Monday?

Answer 1

Answer: The equation to find the number of minutes Alex played on Monday is x+(x+20) = 110 minutes

Explanation:

let the time played by Alex on Monday be represented as x

and the time played by Alex on Tuesday be represented as x+20

Such that the expression to find out the minutes Alex played on Monday given that the total time spent on both days = 110 minutes

Monday +Tuesday = 110 minutes

x+(x+20) = 110 minutes

Solving

x+(x+20) = 110 minutes

2x+20= 110 minutes

2x = 110-20

2x =90

x=90/2=45

x= Amount of time played on Monday =45minutes

x+20 Amount of time played on Tuesday =45 +20= 65 minutes
