Jake and Mike took a different number of tests. Jake scored 85 points on each test. Mike's total score was 15 less than Jake's t
otal score. The following expression shows Mike's total score: 85x − 15 In the expression, what does the variable x represent? (5 points) Select one: a. The total number of tests Mike took b. The total number of tests Jake took c. The sum of Jake's and Mike's total score d. The difference between Jake's and Mike's total score
- The 85 is the score that Jake makes each time. - The x is the number of tests Jake takes. - And the -15 means that you would subtract 15 from Jake's total score (85x) - All this will equal your answer to the equation which is Mikes total score.
The question is asking what does x represent. Therefor the answer would be B. The total number of tests Jake took
The solution of an equation is the value that when substituted for the variable makes the equation a true statement. To achieve our goal, we use two principles of equality, the addition principle and the multiplication principle.
