With a full tank of gas, you can drive 455 miles and your car can go 27 miles per gallon. Write an equation to model this situation (use m for miles you can drive and g for gallons in the tank). (y=mx+b)

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
