Answer:
4.5
Step-by-step explanation:
Since the slope of the equation is 40, we know that for every gallon of gas used, the car travels 40 miles. We know that in total he traveled 180 mi, so if we divide 40 into 180 we can find out how many gallons of gas he used.
180 / 40 = 4.5
so 4.5 gallons of gas were used. To check our work we can just substitute it back into the equation
40 x 4.5 = 180
This equation is true, so now we know that 4.5 gal of gas was used in total. I hope this helps you out :)

Answer:
128
Step-by-step explanation:
There are 16 ounces in a pound. 16 x 8 = 128
For this case we must solve the following linear equation:
Adding to both sides of the equation we have:
Subtracting 17 from both sides of the equation:
Different signs are subtracted and the major sign is placed:
We divide by 14 on both sides of the equation:
