Question

Part A: Solve C = 5 over 9 (F - 32) for F. (4 points)

Part B: Determine the value of F when C = 8 °C. (2 points)

Part C: Solve –np – 80 > 60 for n. Show your work. (4 points)

campbell_st · Answer

ok... so the start for part A is to multiply both sides of the equation by 9 and then divide by 5

so its 

$$\frac{9C}{5} = F - 32$$

you should be able to solve for F now

Part(B) substitute C = 8 into the equation to find F

Part(C) add 80 to both sides of the inequality 

-np > 140 

divide both sides of the inequality by - p

remember, dividing by a negative reverses the inequality. 

hope it helps
