If a kennel has 50 dogs and some of them are puppies and some of them are adult dogs . the ratio of puppies to adult dogs in a kennel are 2: 3 . how many puppies are there?

The ratio is 2:3 puppies to adult dogs, which means for every 2 puppies, there is 3 adult dogs.

Add the ratio together: 2+3 = 5

Divide total dogs by that total: 50 dogs / 5 = 10

Now multiply each number of the ratio by that to find the total number of each:

2 puppies x 10 = 20 total puppies.

3 adults x 10 = 30 total adult dogs.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

answer: 5100 just subtract
