Answer:
The deep of the water would be 20 cm
Step-by-step explanation:
step 1
Find the volume of the water
The volume of the water is equal to
we have
substitute
step 2
Find the deep of the water, if the tank is returned to its horizontal position
(resting on its 60 cm × 100 cm base)
Now we have
substitute the given values
solve for H
therefore
The deep of the water would be 20 cm
Step-by-step explanation:
y = x - 2
x + y = 12
Substitute the first expression for y into the second equation.
x + (x - 2) = 12
2x - 2 = 12
2x = 14
x = 7
Now plug into either equation to find y.
y = 7 - 2
y = 5
So the solution is (7, 5).
