If 6 stones weigh 30 grams, how many stones weigh 55 grams?

11 stones.

Step-by-step explanation:

If 6 stones weigh 30 grams, then 1 stone would be 5 grams.

Fractions are fun so let's do this:

1 stone = x stones

5 grams    55 grams

To get 5 to 55, you multiply 11. So do that on the numerator, and bam, you got 11 stones.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
