Try making up for F, put it in the original equation and find C, then put C in the other equations and seeing is F is the number you made up. (That's what I normally do, it's kind of a brute force tactic, but it can get you through anything)
making up a number for F*
You want me to or are you? Any number?
Any number should work. And I want you to do it.
Do you have a ti calculator by any chance? if so I could teach you a really quick way to do stuff like this.
Yes i do
Alright. If you hit "math" and go to the bottom of the menu, there should be "Solver"
Sorry one second there's a big fat wingspanroach in my room
wingspan? No idea how that got in there
Ah man I'd be freaking out lol
I'm sorry i read it wrong. Is ti a certain type of calculator? /:
Okay. You can put in just about any equation with a missing variable and it will find it. You just have to make the equation equal to 0. So I'd put in 0=(15)-9/5c+32. hit enter then hit ALPHA then ENTER It should show you C.
This is how I got through the SAT. Lol
Oh, yeah, sorry. Ti is.
Sorry I don't have that type.
Uhg, I have to go. The answer is D. Shhhh... I didn't tell you. ;)
It's the reverse basically
Haha :P Thank you (:
Ok, I'll get that type of calculator soon to try that method out.
How are you from SATs?
I'm homeschooled so I didn't have to take them.
Eh, I guess but I feel like I don't learn well online at all. This problem would show how little I know about algebra /:
