In the country of Lao, the distance from Pak Beng to Luang Prabang is 325 kilometers. It takes a riverboat about 7.5 hours to make the trip. The graph shows the distance versus time for a motorboat making the same trip. Approximately how much faster does the motorboat travel than the riverboat?

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

hi how are you doing today, if you need just ask me.

step-by-step explanation:

= 5

step-by-step explanation:

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
