Answer:

x = 7

Step-by-step explanation:

7x-1+6x=90

Combine like terms

13x-1 = 90

Add 1 to each side

13x-1+1 = 90+1

13x = 91

Divide by 13

13x/13 =91/13

x = 7

For number 16 we need to write the data as a ratio then convert to a unit rate (amount per 1)...

308/14 = x/1

Cross multiply

14x = 308
x = 308/14
x = 22

So the fuel efficiency is
22 miles per 1 gallon or

22/1

For number 17, since the car was driven at 48 mph, we just have to divide distance driven by speed to get how long it took...

288 miles ÷ 48 mph =

6 hours
