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

A is the answer i just took the quiz.

Answer 2

Option C is correct

`x+y = 425`

`y = 2x-70`

Explanation:

Here, x represents Kathryn's score and y represents Michael's score.

As per the statement:

Michael and Kathryn bowl together and their combined total score for one game was 425 points.

⇒
`x+y = 425`

It is also given that Michael's score was 70 less than twice Kathryn's.

⇒
`y = 2x-70`

Therefore, the system of equations models the problem is:

`x+y = 425`

`y = 2x-70`
