Rose's age is 3 times the difference of her brother's age and 6. Rose is 15 years old. How old is her brother?

11

Step-by-step explanation:

Rose age = 3(x-6) = 15

Rose's brothers age = x

3(x-6) = 15

3x - 18 = 15

3x = 15+18

x = 33/3 =11

Rose's brothers age = x =11

I hope im rght!!i

11 years old

Step-by-step explanation:

Create an equation where x is her brother's age

15 = 3(x - 6)

Solve for x:

15 = 3x - 18

33 = 3x

11 = x

So, her brother is 11 years old

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
