Ray has found that his new car gets 31 miles per gallon on the highwayand 26 miles per gallon in the city. He recently drove 285
Mkey [24]

Answer:

Highway = 155\ miles

City = 130\ miles

Step-by-step explanation:

Given

Highway = 31mi/gallon

City = 26mi/gallon

Total\ Miles = 285

Total\ Gallons = 10

Required

Determine the number of miles driven on the highway and on the city

Represent the gallons used on highway with h and on city with c.

So, we have:

c + h = 10 ---- gallons used

and

31h + 26c = 285 --- distance travelled

In the first equation, make c the subject

c = 10 - h

Substitute 10 - h for c in the second equation

31h + 26c = 285

31h + 26(10 - h) = 285

Open bracket

31h + 260 - 26h = 285

Collect like terms

31h - 26h = 285 - 260

5h = 25

Make h the subject

h = \frac{25}{5}

h = 5

Substitute 5 for h in c = 10 - h

c = 10 - 5

c = 5

If on the highway, he travels 31 miles per gallon, then his distance on the highway is:

Highway = 31 * 5

Highway = 155\ miles

If in the highway, he travels 26 miles per gallon, then his distance on the highway is:

City = 26 * 5

City = 130\ miles

Name at least two independent variables that could result in a change in a monthly electric bill
CaHeK987 [17]

Answer:

1. The amount of time you keep your porch light on.

2. The temperature you keep your air conditioner at.

Step-by-step explanation:

<u>Porch Light Time Example: </u>

The light does not turn on or off based on the bill, thus its independent, but the bill is effected by the amount of time the light is on thus dependent.

You keep your porch light on for 24 hours a day for 1 month, that month your electricity bill is $50.

Next month you keep your porch light on for 12 hours a day and your electricity bill is $40.

<u>Air Conditioner Temp Example: </u>

The thermostat temperature is not effected by the bill, thus its independent, but the bill is effected by the thermostat, thus dependent.

You set your thermostat to 70 degrees for 1 month, that month your electricity bill is $50.

Next month you set your thermostat to 75 degrees for 1 month, that month your electricity bill is $40.
