Step-by-step explanation:
Where the 2 equations intersect is the solutions to the systems of equations.
If both pipes are opened. Then the number of hours to fill up the tank fully is 100 hours.
The complete question is attached below.
<h3>What are ratio and proportion?</h3>A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Let t be the filling time.
Then we have
Time is inversely proportional to rate of filling tank.
1/20 – 1/25 = 1/t
0.05 - 0.04 = 1/t
0.01 = 1/t
t = 1/0.01
t = 100 hours
