A car travels 340 miles on 20 gallons of gas. How many gallons of gas do you expect it to burn on a 680 mile trip?

the car would burn 40 gallons

Step-by-step explanation:340x2=680 so if a car would burn 20 gallons in 340 then it would burn 40 gallons going 680 miles

hope this helps :)

40 gallons of Gas

Step-by-step explanation:

If 340 miles = 20Gallons

340x2 = 680

20 x 2 = 40

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

f(x)=2/3x-8, which give g(x) the greatest value.
