Find the values of x and y.

Step-by-step explanation:

In the zombie apocalypse, the ratio of children to adults was 3 to 4. The ratio  

of adults to zombies was 4 to 5. If there were 200 zombies, then how many  

children were there?

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

hope this

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
