<span>Treat the surface of the water as 0. The initial height of the weight was 4 ft above the surface of the water, therefore making it have an initial height of +4. If it travels 12 ft downward to hit the bottom of the pool, that means its height decreased by 12, so its falling is -12. To calculate the depth of the pool, use initial height minus drop distance, so 4 - 12. The depth of the pool is 8 ft.</span>
Answer:
3
Step-by-step explanation:
because it's got factors of 64 which when u add gives -12
When you regroup you are basically breaking down the problem.
You would do 60 + 40=?
Then you would do 4 + 3= ?
Your answer would come out to 107
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.
