Let x be the first jug, y the second jug.
From first statement, subtracting 1 from x, makes them equal:
x - 1 = y
From second statement, subtracting 2 from y, makes it half of x:
x/2 = y-2
Solve system with substitution:
x/2 = (x-1) -2
x/2 = x - 3
x- x/2 = 3
x/2 = 3
x = 6
y = x-1 = 6-1 = 5
Therefore the largest jug contains 6 liters.
The simplified ratio of 15:5 is 3:1, divided both sides by 5
Answer:
He needs to get up at 6:30 am.
Step-by-step explanation:
- convert all time to minutes (easier to add times and you can later convert back to hours)
- add all the minutes up
- divide by 60
- subtract the quotient from 9 (since that is the time he needs to get there)
- you should get 6.5 which is 6:30
