A segment is divided into two parts having lengths in the ratio of 5:3. If the difference between the length of the parts is 6", find the length of the longest part.

15"

Explanation:

Let x be the length of the longer part, then the length of the shorter part is 3x/5, or also x - 6

therefore we have the following equation:

3x/5 = x - 6

We can multiply both sides by 5

3x = 5x - 6*5

2x = 30

x = 30/2 = 15"

So the length of the longer part is 15"

he . if i may ask what i your question exactly?

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
