Therefore, the easiest way to think about it is without the absolute value signs at all and just assume every number is positive. When we do this, we can see that the correct answer is C. |-3.5|, |4.2|, |-9|.

Four brothers and their sister have the average age 7. Four brothers have the average age 6. How old is the sister?

AnnyKZ [126]

Answer:

11 years old

Step-by-step explanation:

If four brothers have the average age 6, then the sum of their ages is

$4\cdot 6=24$

years.

Let x years be the age of sister. If four brothers and their sister have the average age 7, then

$\dfrac{24+x}{5}=7.$

Multiply this equation by 5:

$24+x=35\Rightarrow x=35-24=11.$

The sister is 11 years old.
