Question

Part A: Solve F = alt=9/5 C + 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

Part A. The first thing you need to do is isolate C
re work the original equation F=9/5C+32 so that C is one the other side of the = by itself.
First subtract 9/5C from both sides

F-9/5C=32
Then subtract F from both sides

-9/5C=-F+32
Then you have to isolate C by multiplying both sides by -5/9

C=5/9F-283/9

Part B. Plug in 10 for F

C=5/9*10-283/9
C=50/9-283/9
C=233/9
or C=25.89

Part C. Solve -np-70>40 for n

Isolate n
add 70 to both sides

-np>110
then divide by -p

n>-110/p
