5gallons of diesel weighs 37 pounds. how much does 3 gallons of diesel weigh? do these quantities (volume and weight) vary directly or inversely? find the constant of variation.

3 gallons of diesel weighs 22.2 pounds.

The constant of variation is 7.4

The quantities vary directly

Step-by-step explanation:

37/5=7.4 (constant of variation)

7.4*3=22.2

The quantities vary directly because if the amount of gallons go down, so do the pounds. And direct is if x lowers, so does y.

That's correct.

Step-by-step explanation:

I'm pretty sure...
