Answer:
18 hours
Step-by-step explanation:
The unit rate of intake pipe is [1 tank in 6 hours]
The total unit rate (combined) when 2 work together is [1 tank in 9 hours]
Intake fills up and outlet empties. Thus we can say:
Rate of Intake - Rate of Outlet = Combined Rate
This becomes:
Where x is the rate of outlet pipe [what we are looking for]
Doing algebra we solve for x:
This means "outlet pipe can empty 3 tanks in 54 hours". So that would mean 54/3 = 18 hours to empty 1 tank
Answer:
<h2>x = 6, y = 24</h2>Step-by-step explanation:
We have the vertical angles and supplementary angles.
Vertical angles are congruent. Therefore we have the equation:
Supplementary angles add up to 180°. Therefore we have the equation:
Solve (2):
Put the value of x to (1) and sole:
