At 3p. m the temperature is 12 f it then began to drop 2f every hour for 7 hours what is the temperature after 7 hours

The temperature after 7 hours is -2° F

Explanation

At 3 p.m the temperature was 12° F

Then , the temperature began to drop 2° F every hour.

So, the total temperature dropped in 7 hours will be:  ° F

Now, for finding the temperature after 7 hours, we need to subtract the "temperature dropped" from the "initial temperature".

Thus, the temperature after 7 hours ° F

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
