Currently, Nora is 3 time as old as damon. In 8 years she will be only 2 time as old as Damon. How old will Damon will be in 8 y
Ann [662]

In 8 years Damon will be 16 year's old.

We have Nora who 3 time as old as Damon and in 8 years she will be only 2 time as old as Damon.

We have to determine how old will Damon  be in 8 years.

<h3>If your present age is x and your sister is 4 years elder than you. Than what will be her age after 5 years from now.</h3>

Your present age = x.

Hence, your sister's present age = x + 4.

After five years, your age = x + 5.

Hence, your sister's age will be = x + 9.

According to question, we have -

Assume that the present age of Damon is x.

Then, Nora's age will be = y = 3x.

After 8 years -

Damon's age = x + 8

Nora's age = 3x + 8

Therefore -

3x + 8 = 2(x + 8)

3x + 8 = 2x + 16

x = 8

Hence, in 8 years Damon will be = 8 + 8 = 16 year's old.

Inessa05 [86]

Step-by-step explanation:

A.) Ok, so the mean price for Southtown is 72,800.

And the mean price for middle town is 54,900

So Southtown has the higher mean price.

Explanation:

To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.

72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000

Then,

364,000/ 5 = 72,800

B.) It is 17,900

Explanation:

72,800 - 54,900 = 17,900

Hope this helps you out!!! : )
