One tank contains 50 gallons of water and another tank contains 75 gallons of water. water is draining out of both tanks at a rate of 6 gallons per minute. do the tanks ever have the same amount of water before either is empty

No

Step-by-step explanation:

The tanks have separate amounts of starting amounts and they are depleting at the same rate, meaning that they will never be the same.

You can also do it like this:

The volume of the first tank can be modeled by y = x + 50

The volume of the second tank can be modeled by y = x + 75

Now find when they are equal by setting the equations to each other.

x + 50 = x + 75

x = x + 25

0 = 25

This equation has no solution

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer: b
