Question 1210263: A water gallon weighs 5 kg when it is filled with water. When the gallon is half empty, it weighs 2.6 kg. How much does the gallon weigh when it is empty? Found 4 solutions by greenestamps, ikleyn, josgarithmetic, timofer:Answer by greenestamps(13200) (Show Source):
The container with the gallon of water weighs 5 kg.
When half of the water is emptied, the container and the remaining water weigh 2.6 kg. So the weight of the half gallon of water that was emptied is (5-2.6) = 2.4 kg.
The weight of the half gallon of water that remains in the container is also 2.4 kg.
Since the combined weight of the container and the remaining half gallon of water is 2.6 kg, the weight of the container alone is (2.6-2.4) = 0.2 kg.
You can put this solution on YOUR website! You wrote that wrong. Say it like this:
A water container "weighs" 5 kg when filled full with water. When the container is half empty, it holds 2.6 kg of water.
x, amount filled
y, how much kilograms in container
Two points are (0.5, 2.6) and (1, 5).
Slope would be .
Point-Slope equation format could be used.
So if container were empty, x=0, so y=0.2.
The container is 0.2 kg when empty.
