Martina has two dogs. The ratio of the dogs’ weights is 2:3. If the total weight of the two dogs is 40 pounds, how much does each
dog weigh?

The dogs' weights are 16 pounds and 24 pounds

Step-by-step explanation:

Equations:

Martina has two dogs. Their combined weight is 40 pounds. Let's set:

x       = weight of one of the dogs.

40-x = weight of the other dog

The ratio between them is 2:3, thus:

Cross multiplying denominators:

3x = 2(40 - x)

Operating:

3x = 80 - 2x

Adding 2x:

5x = 80

Dividing by 5:

x = 80/5 = 16

x = 16 pounds

The weight of the other dog is 40-16=24 pounds.

The dogs' weights are 16 pounds and 24 pounds

i think it would be 42cm

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
