14. Jonathan's car gets approximately 25 miles per gallon. He is planning

980-mile trip. About how many gallons of gas will his car use for

the trip? At an average price of $4.00 per gallon, how much should

Jonathan expect to spend for gas? Round to the nearest ten dollars.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
