Answer:

12

Step-by-step explanation:

x will be the age of her younger brother

 34 = 2x + 10

She is ten more than twice his age

 34 = 2x + 10

- 10         - 10

Then she twice his age

24 = 2x

÷2   ÷2

So his age is 12

x = 12

Use proportion to find the whole 75 is 15% of what number
Iteru [2.4K]

Answer:

500

Step-by-step explanation:

15% * x = 75

(15/100) * x = 75           Multiply both sides by 100/15

(15/100)*(100/15) = 75 * 100/15

x = 7500/15

x = 500

Answer 500

Proportion

15/100 = 75 / x             Cross multiply

15x = 100*75                Combine the right

15x = 7500                   Divide 15

15x/15 = 7500/15

x = 500
