Answer:

The answer is the option A

(4,6)

Step-by-step explanation:

we have

4x=3y-2 -----> equation A

18=3x+y ----> isolate the variable y

y=-3x+18 -----> equation B

Substitute the equation B in the equation A

4x=3(-3x+18)-2

4x=-9x+54-2

4x+9x=52

13x=52

x=4

substitute the value of x in the equation B

y=-3(4)+18=6

therefore

the solution is the point (4,6)

Nuetrik [128]

Answer:

180 miles

Step-by-step explanation:

Step one:

capacity of tank= 18.5gallons

vehicle averages 666 miles per tank.

Hence, the vehicle can travel 666 miles on 18.5 gallons

Required

The distance covered on 5 gallons

Step two:

vehicle can travel 666 miles on 18.5 gallons

the vehicle will go x miles on 5 gallons

cross multiply we have

5*666= 18.5*x

3330=18.5x

divide both sides by 18.5

x= 3330/18.5

x=180 miles
