It is currently 0 degrees outside, and the temperature is dropping 4 degrees every hour. The temperature after h hours is -4h. Explain what the equation -4h = -14 represents.

⇒ Temperature dropping per hour

⇒  Number of hours.

⇒ Temperature after 'h' hours

Step-by-step explanation:

Given:

Current temperature = 0 degrees

Temperature dropping per hour = -4 degrees.

Temperature after h hours =

We need to explain what the equation represents.

Solution:

Now we know that;

Temperature after h hours =

Now we know that;

Current temperature is 0 degrees and temperature is decreasing at a rate of -4 degrees per hour so if we multiply -4 from h which number of hours it will show the temperature after h hours.

So we can say that;

-14 will be the temperature after 'h' hours in equation  .

where;

⇒ Temperature dropping per hour

⇒  Number of hours.

⇒ Temperature after 'h' hours

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
