QUICK HELP PLEASE SHOW WORK THANKS
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

1 1/5

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
