@StrawberryArmada Alright dude I looked over it, left my comments and some sources I found. Hopefully someone else can give it a once over as well @here
Thanks mate. I still have a week before the finally draft
yw!
Anyone able to help with an algebra problem? Pretty basic
@Warren H shoot
9u = 6/5
How do i get to 2/15?
Multiply both sides by 5
so on the left you have 45 u
an the right the 5 on the bottom cancels out with the 5 on the top you just multiplied
so 45u = 6
then divide both sides by 45
so u = 6/45
6 is 2\*3, and 45 = 15\*3
so u = (2\*3)/(15\*3)
the 3 on top and bottom cross out
so u = 2/15
@Warren H oh you want it the way they did it in the picture? it is similar:
Your way seems easier. There's was confusing as heck
How did you know 15 x 3? Instead of 9x5?
I'm bad with fractions lol
I'll do it closer to the way they did it:
starting from 9u = 6/5
divide both sides by 9, so u = (6/5) * (1/9)
so u = 6/(5*9)
now 6 is 2\*3 and 9 is 3\*3
so u = (2\*3)/(5\*3\*3)
cross out a 3 on top and bottom
Ohh okay.
so u = 2/(5*3)
so u = 2/15
yep
So I do that every time? Divide both sides by whatever the number is?
Yep that will always work
Awesome thanks. One more, this one is a negative number. I'm guessing it works the same?
-4w = 6/7
So divide both sides by -4 and I get 6/7 * 1/4? Or -1/4
Yep:
divide both sides by -4, so w = 6/(7* -4)
6 is 2\*3 and -4 is 2\*-2
so w = (2\*3) / (7\*2\*-2)
then cross out the two on top and bottom
so w = 3/(7*-2)
so w = 3/(-14) or equivalently w = -3/14
@Warren H the second one
the negative sign stays with the number it is attached to
