Kenny's weight is 6/7 times melvin's weight. what is the ratio of melvin's weight to the total weight of the two boys?

dangina [55]

Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7
divide both sides by 6/7
Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...
7+6=13

So Melvin's weight over the total weight of the two boys is:

7:13

Answer:

9) y = -x + 5

10) y = -7/2x - 5

11) y = x - 1

12) y = -5x/3 - 3

13) y = -4x/1

I'm not 100% sure for some of these answers since the pic is a bit blurry, but they're pretty accurate.
