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: l

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
