togheter they have 115 caps. how many baseball caps does each of them have?
i got: melinda has 54 mark has 61

i have 2 more i cant figure out:
1) in a pet store the number of dogs is more than 3 times the number cats. if the pet store has 21 dogs how many cats does it have?

2) in the pet store the number of birds is 10 less than twice the number of rabbits, if the pet store has 56 birds, how many birds does it have?

Answer 1

1) yes I think is right

2) 21x3=63

3) Not quite sure it doesn't make any sense

Answer 2

for question 1 is it 9 cats

Answer 3

The first one is right.

1) The store has less than 7 cats.

2) 56 - 10 = 46
46/2 = 23

Answer 4

so question 1
is 7 cats
i don't follow how you got 7?

question 2 is 23 rabbits

Answer 5

21 dogs

21 = 3c

Solve for c

Answer 6

3x 7 = 21
so c = 7
i get it
