Dave drives a delivery truck. The relationship between the number of gallons of gas in the tank y, and the number of hours that the truck can be driven r is modified by the function y = 3r+30 If the tank is full, how long can Dave drive his truck before he runs out of gas?

Jayne stopped to get gas before going on a road trip. The tank already had 4 gallons of gas in it. Which equation relates the total amount of gasoline in the tank, y, to the number of gaes a delivery truck. The relationship between the number of gallons of gas in the tank y, and the number of hours that the truck can be driven r is modified by the function y = 3r+30 If the tank is full, how long can Dave drive his truck belationship between the number of gallons of gas in the tank y, and the number of hours that the truck can be driven r is modified by the function y = 3r+30 If the tank is full, how long can Dave drive his truck b

f

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
