[2.08] The formula for degrees Celsius is: C = 9 over 5 (F − 32), where F stands for degrees Fahrenheit. Part 1: Solve the formula for F. Show all steps. Part 2: Determine how many degrees Fahrenheit 4 degrees Celsius is.

i thought it was 5/9?
dmezzullo
  • dmezzullo
it is
AriPotta
  • AriPotta
but you wrote 9/5. i'm just making sure
AriPotta
  • AriPotta
idk :/ it's probably 9/5, nvm
swissgirl
  • swissgirl
can u draw the equation cuz I so dont follow it

Now our first step would be to isolate our F
AriPotta
  • AriPotta
it's 5/9 now? ugh
swissgirl
  • swissgirl
So first we divide the 5/9 \(\large C*\frac{9}{5} = \frac{5}{9}*\frac{9}{5} (F-32)\) \(\large \frac{9}{5}C=F-32\) Then we add 32 to both sides: \(\large \frac{9}{5}C+32=F-32+32\) \(\large \frac{9}{5}C+32=F\) And there you go there is your formula for F

ohhh whoops I meant multiply instead of divide
dmezzullo
  • dmezzullo
this didnt come from google right?
swissgirl
  • swissgirl
Ok that first line should say: So first we multiply both sides by 9/5
swissgirl
  • swissgirl
hahaha Noooooooooo I just did it this second. I taught grade 11 HS math last year lol
swissgirl
  • swissgirl
All I did was isolate the F. Its a basic tool which is needed quite often in algebra
swissgirl
  • swissgirl
The way i would suggest you learn how to isolate is by starting off with simpler functions such as y=3x+4 And try to isloate the x.

Now Part B all its asking for you is to find out what 4 degrees Celsius is in Faranheight. Now which equation would you use?
dmezzullo
  • dmezzullo
idk
swissgirl
  • swissgirl
Ok the equation we just figured out
swissgirl
  • swissgirl
We would like to know what F=Fahrenheit equals when c=4 \(\Large F=\frac{9}{5}C+32\) So we plug in C=4 \(\Large F=\frac{9}{5}(4)+32\) Ok now you solve the rest
dmezzullo
  • dmezzullo
No
swissgirl
  • swissgirl
\( \large F=\frac{36}{5} +32 =39.2\)
