Answer:
e=2
Step-by-step explanation:
7(2e−1)−3=6+6e
Distribute
14e -7 -3 = 6+6e
14e -10 = 6+6e
Subtract 6e from each side
14e-6e -10 = 6+6e-6e
8e -10 =6
Add 10 to each side
8e -10+10 = 6+10
8e = 16
Divide by 8
8e/8 = 16/8
e=2

Answer:
It take 37.5 hours to fill the tank
Step-by-step explanation:
Given:
Time Taken to fill the tank = 15 hours
Time Taken to empty the tank = 25 hours
To Find:
Time taken to fill the tank when both the inlet and outlet is opened at the same time = ?
Solution:
Let the time to fill the tank be x
In 15 hours the tap fills the tank
Rate at which the tank is filled =
In 25 hours the tap empties the tank
Rate at which the tank is drained =
The net gain per minute on the total filling rate is
=> Rate at which the tank is filled - Rate at which the tank is drained
=>
=>
=>
=> 10x = 375
=>
=>x = 37.5
