° was the temperature,in degrees at 7 pm .

Step-by-step explanation:

Here we have , at 3 pm ,the outside temperature was 4 degrees f .the temperature then fell steadily by 2 degrees every hour for the next four hours. We need to find what was the temperature,in degrees at 7 pm .Let's find out:

At 3 pm , Temperature was 4° . Then , temperature then fell steadily by 2 degrees every hour for the next four hours , Total decrease in temperature:

⇒ 2(4)

⇒

So , In next 4 hours after 3 pm there is decrease in 8° temperature , But initially temperature was 4° , So , Temperature after 4 hours i.e. at 7 pm :

⇒ 4-8

⇒ °

Therefore , ° was the temperature,in degrees at 7 pm .

The temperature at 7 pm is -4 degrees, if the temperature at 3 pm is 4 degrees then it fell steadily by 2 degrees every hours for the next four hours.

Step-by-step explanation

The given is,

At 3 pm the outside temperature was 4 degrees

Then it fell steadily by 2 degrees for every hour, for the next four hours.

Step:1

Let, T - Temperature

The temperature at 3 pm,

T = 4 degrees ( ∵ from given)

Step:2

Temperature at 4 pm,

T = (4 - 2) degrees (∵ steadily fell 2 degrees for each hour)

= 2 degrees

Temperature at 5 pm,

T = (2-2) degrees

= 0 degrees

Temperature at 6 pm,

T = (0-2) degrees

= -2 degrees

Temperature at 7 pm,

T = (-2 - 2) degrees (∵ both signs are same (negative), so we add the two numbers)

= -4 degrees

Result:

The temperature at 7 pm is -4 degrees, if temperature at 3 pm was 4 degrees, then it fell steadily by degrees every hours for next four hours.
