Question

Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s. What were their scores?

Which is a system of equations to model the problem if x represents Kathryn’s score and y represents Michael’s score?

A.
x + y = 70
y = 2x – 425

B.
x – y = 425
y = 2x – 70

C.
x + y = 425
y = 2x – 70

D.
x + y = 425
y = 2x + 70

Answer 1

I think it is B. but I'm not sure

Answer 2

its close

Answer 3

@Ms-Brains

Answer 4

C is the correct answer??

Answer 5

yea

Answer 6

I'd strongly suggest you set up the equations yourself and then decide how you're going to solve this system of equations. You learn little or nothing asking, "Is C the correct answer?"

Answer 7

im srry its my falut

Answer 8

i dint mean to

Answer 9

Please do your best to set up the 2 equations required here.
One equation should be in bowling scores.
The other equation should show by how much one person's score exceeds the score of the other person.

Let m=Michael's score; let k=Kath's score. How are these 2 scores related?

Answer 10

Let me guess algebra

Answer 11

yes, it's algebra. If you've done well in Algebra, please contribute some concrete suggestions so that Ms-Brains can complete the solution.

Answer 12

Guys. chill. I'm done with this problem. I'm about to post a new one.

Answer 13

The best way to solve word problems is to list the problems out before attempting to solve it.....Then the solution would be easy to solve

Answer 14

but u are right
