N=32a+30=58b+44.
Chinese remainder theorem whould have been useful, but you won't get it. So, you've got something more complicated in there...
Well, you get numbers 30, 62, 94, 126, 158, 190, 222 etc for the first one and 44, 102, 160, 218 etc for the second one...
I just can't do without that one! :)) The main idea is that you could calculate all numbers under 3000 in both conditions: the lists only share our number (supposedly :)) )
Answer:
top is 13 gallons left
bottom is 7.8 gallons left
Step-by-step explanation:
30=1 gallon
90= 3 gallons
246/30= 8.2
8.2*1=8.2
16-8.2=7.8
Answer:

To “distribute” means to divide something or give a share or part of something.
Answer:
The present age of Joyal is 14 years.
The present age of Joyal's mother is 42 years
Step-by-step explanation:
Let J denotes the age of Joyal
Let M denotes the age of Joyal's mother
The present age of Joyal’s mother is three times the present age of joyal.
Mathematically,
M = 3J
After 5 years their ages will add up to 66
Mathematically,
(M + 5) + (3J + 5) = 66
M + J + 10 = 66
M + J = 66 - 10
M + J = 56
But we know that M = 3J
3J + J = 56
4J = 56
J = 56/4
J = 14 years
So the present age of Joyal is 14 years.
M = 3J
M = 3(14)
M = 42 years
So the present age of Joyal's mother is 42 years.
