Question

Hi! I REALLY need help in this one. It is super important.

Part A: Solve C = (F - 32) for F.

Part B: Determine the value of F when C = 8 °C.

Part C: Solve -np - 80 > 60 for n. Show your work.

Medal and Fan for the correct answer. Please, I REALLY need this.

Answer 1

Part A: Solve C = (F - 32) for F.
Add 32 to both sides.
C + 32 = F or F = C + 32
Part B: Determine the value of F when C = 8 °C.
Using F = C + 32 plug in C = 8
F = 8 + 32
F = 40
Part C: Solve -np - 80 > 60 for n. Show your work.
Not sure I understand this one completely, it doesn't look like it is related to the others.
-np - 80 > 60
add 80 to both sides
-np > 140
Divide both sides by p
-n > 140/p
Multiply both sides by -1 (need to change direction of > sign when you do this)
n < -140/p

Answer 2

usually giving direct answers is against code of conduct but I'm not in the mood to have that enforced, so nice job :D

Answer 3

thx!

Answer 4

Thanks so much for your help! You are an absolute life-saver!

Answer 5

You're welcome. I hope you understand how I solved it and can use that approach next time.

Answer 6

Are you sure about the formula in part A?

I think you missed a 5/9

$$\Huge C=\dfrac{5}{9}(F-32)$$

Answer 7

I agree with skullpatrol. If you are trying to convert from degrees C to degrees F or visa versa you need the scaling factor of 5/9.
