Question

Jake and Mike took x tests each. Mike scored 15 points less than Jake. The expression below shows Mike's total score in the tests:
85x - 15

What does the coefficient of the expression represent? (3 points)


The total score Jake earned
The sum of Jake's and Mike's total score
The score Jake obtained in each test
The difference between Jake's and Mike's total score

Answer 1

in the real world this question makes no sense, but for the sake of the question assume jake got the same score on every one of his tests and that mike also got the same score on every single test. Mike's score multiplied together are 15 points less than Jake's score multiplied together.

Answer 2

i dont get it @caominhim

Answer 3

say i get a 50 on 3 tests. If i add all my points together i'll get 50+50+50. Or i could say i got 50*3.

my friend's total was 75 points less than mine because he got 25's on his 3 tests. 25+25+25, or 25*3.

Answer 11

I really can't explain any more without straight up telling you the answer, look at my comment and determine what i multiply x by, that is the answer.
