Direct variation is of the form y=kx, where k is the constant of variation. It is "direct" because as x increases/decreases so does y in the same magnitude.
y=kx, In this case the dependent variable y, is miles and the independent variable x, is gallons. We are told that the car gets 28mi/gal so
y=28x
Step-by-step explanation:
1. Multiply 18.5 by 6.

Therefore, the answer is A. 18.25
3,062.85 is de answer having on two decimals
Answer:
a) (-1/2,3/2)
Step-by-step explanation:
