hopefully that makes it easier to deal with?
I suck at math big time... mainly algebra... but I remember some of the simpler stuff
Would you times everything by 3 to isolate r?
@HUNTER4639 with what I did to #10, is that any easier to figure out?
Algebra 2 @Wardog
I think so
hmm. so with the r situation, youd times everything by the inverse I think... that part is a little foggy to me...
so youd want to do something like multiple everything with the denominator of 3 by 5, and everything with the denominator of 5 by 3 (so it all comes out to something over 15.
I forget exactly how to do that though. and fuck algebra 2. my worst math class and worst subject ever... only class I EVER came anywhere close to failing.
Ehh Geometry was harder for me loool then again this is only the 2nd week of Algebra 2...
Alrighty thanks for the help everyone <:TrumpSmile:720121948088041513>
bruh, I rocked at geometry. it seems like a lot of people are really good at algebra, OR geometry.
happy to help man
😀
...
#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?
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
