Question

Guys help!!!! !Part A: Solve F = 9/5C + 32 for

c. (4 points) Part B: Determine the value of C when F = 10 °F. (2 points) Part C: Solve -np - 70 > 40 for n. Show your work. (4 points)

Answer 1

A:

`F=(9)/(5)C+32 \\ \\ F-32=(9)/(5)C \\ \\ \boxed{C=(5)/(9)(F-32)}`

B:

`F=10^\circ F \\ \\ C=(5)/(9)(F-32)=(5)/(9)(10-32)=(5)/(9) * (-22)=(-110)/(9)=-12(2)/(9) \\ \\ \boxed{C=-12 (2)/(9) ^\circ C}`

C:

`-np-70\ \textgreater \ 40 \ \ \ \ \ \ |\hbox{add 70} \\ \\ -np\ \textgreater \ 110 \ \ \ \ \ \ \ \ \ \ \ |\hbox{divide by (-p), flip the sign} \\ \\ \boxed{n\ \textless \ -(110)/(p)}`
