Question

convert degrees Fahrenheit (F) into degrees Celsius (C) use the formula C = 5/9(F - 32) Rewrite the equation to convert degrees Celsius to degrees Fahrenheit.

Answer 1

@JA1

Answer 2

Ok so we have the formula already:

\[C = \frac{ 5 }{ 9 } (f - 32)\]

Answer 3

A. F = 5/9(C - 32)
B. F = 9/5 C - 32
C. F = 5/9 C - 32
D. F = 9/5 C + 32

Answer 4

So how can we make this do the opposite and convert C to F?

Answer 5

Add, or multiply? By doing opposite.

Answer 6

Not quite, we simply have to switch the terms to be the opposite.

Answer 7

So first let's switch it term by term, the first term is: \[C =\] so we have to switch it to:\[F =\] since we are looking for F.

Answer 8

C = 5/9 & F = - 32

Answer 9

Now the next term is: \[\frac{ 5 }{ 9 }\] and since we are doing the opposite we switch the fraction so what would the end product be?

Answer 10

Not quite.

Answer 11

See, I am lost. (/.\)

Answer 12

xD ok so we just switched

\(C~=\)

into :

\(F~=\)

So what do we switch

\[\frac{ 5 }{ 9 }\]

into?

Answer 13

F?

Answer 14

Remember we are doing the opposite.

Answer 15

Not quite, just reorder the fraction to be the opposite :)

Answer 16

5/9 opposite = ?

Answer 17

9/5

Answer 18

Exaclty :)

Answer 19

So, it's B.

Answer 20

So we now we have:

\[F = \frac{ 9 }{ 5 }\]

Answer 21

Not yet...

Answer 22

no, its D because we are doing the opposite by adding 32!

Answer 23

Ok so the last equation had:
\[(F - 32)\]so what is the opposite of that?

Answer 24

PERFECT

Answer 25

:D

Answer 26

(F + 32)

Answer 27

See you got this just takes some practice

Answer 28

LOL, it's just I need someone to help me through it.

Answer 29

Not quite, remember we are looking for F so it is (C + 32)

Answer 30

Yupp you just need a good understanding :)

Answer 31

Thank you so much you're really helping me. So it's D.

Answer 32

No problem :) and medal would be appreciated ^,^

Answer 33

tu :)
