Answer:
x = 12 hrs to fill the pool
Step-by-step explanation: INCOMPLETE QUESTION
Missed information:
Time for two different sizes hoses to fill a small simming pool (let say that is 3 hours)
Time for one of the two hoses to fill a small simming pool ( lt say that is 4 hours)
With that information we can answer the question
If one of the hoses fill the pool in 4 hours, it will fill 1/4 of the pool in 1 hour
We dont know the other hose how long it take to fill the pool so let call that time x hours then in 1 hour it will fill 1/x of the pool
In 1 Hour the two hoses will fill 1/3 of the pool then
In one hour
1/4 + 1/x = 1/3 Solving for x
( x + 4 )/ 4x = 1/3
3x + 12 = 4x
- x = -12 x = 12 hours
36 divided by 6 is like sharing 36 orranges among 6 people

Each person receives 6 oranges evenly so 36/6 = 6

Answer:
Step-by-step explanation:
This is awfully hard to read. Use returns to separate paragraphs.
ax = bx + 1 Subtract bx from both sides.
ax - bx = 1 take out x as a common factor
x(a - b) = 1 Divide both sides by a - b
x = 1 / (a - b)
I think the second one is the one you want.
x is the same as the reciprocal of the difference between a and b.
