6-70.

picTo solve the following problem, use the 5-D Process. Define a variable and write an expression for each column of your table.

In the first three football games of the season, Carlos gained three times as many yards as Alston. Travis gained ten yards more than Carlos. Altogether, the three players gained a total of yards. How many yards did Carlos gain? Homework Help ✎

 

 

 

Based on the information from the problem, two of the players, Carlos and Travis, can be directly related to Alston in yardage. If Alston's yards are represented by the variable, , how can Carlos and Travis' yards be represented?
