Question

Which are valid rearrangements of F = 9/5C + 32? Select the two correct answers F - 32 =9/5C C = 9/5(F-32)9/5C- F = 32 C=5/9(F-32)F+9/5C + 32 = 0

Answer 1

We have the following:

`F=(9)/(5)C+32`

1. F - 32 =9/5C

`\begin{gathered} F-32=(9)/(5)C \\ F=(9)/(5)C+32 \end{gathered}`

It's correct.

2. C = 9/5(F-32)

`\begin{gathered} C=(9)/(5)\left(F-32\right) \\ (5)/(9)C=F-32 \\ F=(5)/(9)+32 \end{gathered}`

It's not correct.

3. 9/5C- F = 32

`\begin{gathered} (9)/(5)C-F=32 \\ F=(9)/(5)C-32 \end{gathered}`

It's not correct.

4. C=5/9(F-32)

`\begin{gathered} C=(5)/(9)\left(F-32\right) \\ (9)/(5)C=F-32 \\ F=(9)/(5)C+32 \end{gathered}`

It's correct.

5. F+9/5C + 32 = 0

`F=-(9)/(5)C-32`

It's not correct.

The options corrects are F - 32 =9/5C and C=5/9(F-32)
