#10 r is 72/5
-16/5 = r/3 -8
Add 8 to both sides, multiply 8 by 5 to slide it into the top of the fraction on the left
(40-16)/5=r/3
24/5=r/3
Multiply both sides by 15 to cancel out both denominators
72=5r
divide both by 5, get r
72/5=r

Do fuck am I late to the party

wait how do you go from 24/5=r/3 to 72=5r? its been a while, but I dont understand how exactly how got to that

Multiply both by 15

you would multiply 24/5 by 15/15 right?

5 cancels out left bottom, so 24*3

oh wait, 15/1

nah, 15/1

ohhhh okay. i remember now

not 15/15 because thats 1, 15/1 makes 360/5 which reduces to 72

okay

fuck I hate math lol

I'm fine with it until they add the greek letters, fuck that noise

and I guess I was wrong? multiplying both sides by 15 works the same as multiplying both sides by the inverse to get common denominators, right?

It's the same

I just said 15 cause it is the end result

okay, but doing it by 15 is quicker and has less steps

Yep

gotcha!

Mark out he denominators and cross-apply them

Or something

I may not be sober

ohhhhh wait, I see, you skipped steps and just went ahead and multiplied the numerators by 15 instead of doing the shit I said by multiplying all of them. same exact thing, but you skipped a couple steps. one of my greatest weaknesses in math was skipping steps. couldnt skip any of them without getting horribly confused

My brain just auto pilots on most stuff

nice to be reminded of this stuff a little bit though, every so often its nice to get a refresher... especially since im so bad at it lol.

and no worries man, youre right I just couldnt figure it

> fuck I hate math lol
@Wardog If I were a mod, I’d ban you for this 😡

It's truth

You’ve been listening to too much Jimmy Buffett!

Math is great

Without math, how would we know what percentage of the population commits what percentage of the violent crimes?

Math teaches a lot of logic. It is very useful that way

Too bad SJW’s are trying to ruin math.

It used to be fun stuff, like numbers like 142,857 and 6,174.

Everything is math and chemicals. *EVERYTHING*.

Now it’s “if x is the number of cops, and y is the number of bastard cops, then x=y”.

political compass meme of how I am seeing this world, in people/groups out there and people that I know. (WIP)

nazis were left of the spectrum

economically right but politically left

the super hardcore centrists ive met have almost always been incredibly stuck up, self righteous assholes that literally use "well I dont pick sides" in debates/arguments and think that saying that supports whatever bullshit theyre saying. enlightened centrists like that sicken me tbh.
