Answer:
22
Step-by-step explanation:
Let X be the time for only a small drain, the work completed would be unity.
The small drain has been open for a total of 11 hours, one hour next to the large one, and 10 hours alone.
We have that large drainage can accomplish this in 2 hours.
We have the following system:
1/2 + 11 / x = 1
solving, we have:
11 / x = 1 - 1/2
11 / x = 1/2
x = 11 * 2
x = 22
I mean it would take a total of 22 hours for the small drain alone
It is a composite number and it is written as 7*3*5*2
In a football game a team might move up 20 yards but they might get a penalty for something and push them back 15 yards.
Hope this helps. I'm just in a rush.
Answer:
[1] 9x - 4y = 7
[2] x - 4y = -17
[2] x = 4y - 17
// Plug this in for variable x in equation [1]
[1] 9•(4y-17) - 4y = 7
[1] 32y = 160
// Solve equation [1] for the variable y
[1] 32y = 160
[1] y = 5
// By now we know this much :
x = 4y-17
y = 5
// Use the y value to solve for x
x = 4(5)-17 = 3
