ANSWER:

Integer 6 represents the change in the number of gallons of gas in your tank after driving 3 hours

Solution:

Given, Let's assume that your car burns 2 gallons of gas every hour.  

We need to find the integer that represents the change in the number of gallons of gas in your tank after driving 3 hours.

Let, the initial amount of gas in our car be x gallons.

Then, for every one hour,car consumes 2 gallons.

So, we need to subtract 2 from initial gas, i.e. x

gas after one hour = x – 2

Now, we have to find after 3 hours.

So, gas after three hours = x – 3 x (gas consumed in one hour)

= x – (3)(2 ) = x – 6

Gas in car after 3 hours = x – 6

Change in gas = initial gas – final gas

= x – (x – 6)  = x – x + 6  = 6

Hence, the integer representing the change in gas is 6.  

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

well the answer to that is xoxoxo
