Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
10.5*5= 52.5 is the correct answer to the question
1. You have the function 
2. You know that
with
, because the division by zero is not defined. So ,
for
where
is a integer number.
3. Then, to find the domain of the function given in the problem, you must make 
Where
is odd number.
4. Therefore:

5. Finally, the domain is: 
The answer is: 
You are looking for the circumference. which is C(circumference)=

x r (radius)
the radius is =to half of the diameter.
c=56.55
2 litres every 2.5 minutes is 4 litres every 5 minutes so therefore, it is 0.8 litres/minute (800ml per minutes)
