Working together, two pipes can fill a swimming pool in 4 hours. Working alone the larger pipe can fill the pool in 6 hours. How many hours would it take the smaller pipe working alone to fill the swimming pool.

12 hours

Step-by-step explanation:

The computation of the number of hours does the smaller pipe takes for working alone is shown below:

Given that

Total time taken for both types is 4 hours

And, the larger pipe alone can take 6 hours

Now for the smaller pipe we assume x

So,

x = 12 hours

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

5/20 so 25%
