Need help on this Algebra 2 equation

sonicsfan

lol... well yeah I suck at algebra, now who cant figure that out... I can make all A's in all my classes except this class... I understand a lot of it but stuff like this is hard for me

Solve for "F"

C = 5/9 ( F - 32 )

I know I have to get the F by itself...
and I got by order of operations, which the ( ) would be first... so do I divide or what?



I posted new problems at the bottom

Colt

Geez man, what you gonna do when you got a test on this stuff?

Colt

I havnt had math for 2 years but i think you can
Multiply by 1
Add 32
then subtract 5/9

That would be F= C+31 4/9

but then again its been along time lol

sonicsfan

we already got a test yesterday, I made like an 83 on it
but there was only 1 problem with this type of stuff

sonicsfan

the answer is F = 9/5 C + 32
but I cant get to show work on it

sonicsfan

will this shortcut work all the time-

do the reciprical of 5/9, which makes 9/5 and put it on the C side... and change the sign of the - 32 to + 32 on that C side?
but not sure if its correct everytime

thematrix31

this is how you do it...

Solve for "F"

C = 5/9 ( F - 32 )



1) Multiply both sides by 5/9

2) Add 32 to both sides

3) answer should be F=(5/9)c-32

sonicsfan

in the back of my book it says F = 9/5 C + 32

it will help.


get off the internet and do your homework. LOL

Just kidding.

I haven't had algebra since college.

Jason

all that you did there to get the answer: F = 9/5 C + 32
is swap the stuff, C = 5/9 ( F - 32 ) u just switched..
1) switch letter position
2) reciproal 5/9 to 9/5
3) switch the sign to a negative since postive.

I'm on the internet and working... I am like 4 probs past that now
thanks guys

ok, new problems came up...
I need to figure out how to set up equation

25) You have a leaky faucet at home that fills an 8 ounce glass (0.03 gallon) in 12 minutes.
How much water would drip from this faucet IN ONE YEAR?

27) An average 10 minute shower uses 50 gallons of water.
In a YEAR, how many showers are "lost". ?

Colt

it would fill 219,000 glasses or 6,570 Gallons

The second question dosn't make sense........I had sex in the shower once, just had to throw that out there. LMAO

How could you lose a shower isan;t it attached in your house??? lol

sonicsfan

we dont have to work that last one... lol, I accidently put that one in there but it'd be nice to know how to figure it out
in the book, that one is 1314 gallons

lol @ the wasted water sex

sonicsfan

o well... she only grades our homework by how many we got done... so I can kinda try and that one and leave it and get credit... she'll show us how to work it tomorrow in class

i'm 13 and i'm helpin you ...

you need to find how many mintues are in a year...


12 min x 5 = 60 minutes (1 hr.)

60 min (1 hr.) x 24 = 1,440 mins (1 day)

1,440 (1 day) x 365 = 525,600 minutes (1 year)


now.... the trickier part


8 x 12
n x 525,600

find the value of 'n'... you people can do that...

hope that helps
