Question

r= 2/3t+v , solve for t
Show work please, I'm stressing out on some of these problems... thanks :)

Answer 1

r=2/3t+v so to solve for T.. first take minus the V on both sides like this v-r=2/3t you following this??

Answer 2

next because we are solving for T we divide by 2/3 to get T my itself. so we have v-r/2/3=t

Answer 3

hope this helps...

Answer 4

Thank you so much!

Answer 5

not a problem any questions before I leave?

Answer 6

I have one last problem thats bugging me and that is -14n+q=rt-4n, solve for n.

Answer 7

first what do you know already

Answer 8

do I need to subtract rt from both sides?

Answer 9

yes you can do that, but we to collect a like terms first

Answer 10

Oh! The -14n and the -4n can go together.

Answer 11

yes, but be careful here what happens with the sign when it crosses the equal? recall + becomes - and - becomes +

Answer 12

So, 18n+g=rt ?

Answer 13

that is correct

Answer 14

so now what do we need to get N standing alone?

Answer 15

hint look at the g.

Answer 16

subtract the g on both sides, leaving me with 18n=rt-g

Answer 17

yes

Answer 18

then divide by 18 to get n=rt-g/18 ?

Answer 19

Nice job

Answer 20

Thank you SO much! I understand it now! :D You're a lifesaver.

Answer 21

I want to be sure you understand so ask questions if you have any?

Answer 22

Okay, I have another problem that I know how to start off but not finish.
ax+z=aw -y
+y +y
And that gives me ax+z+y=aw And thats where I'm not sure where to go from there...

Answer 23

what are we solving for or what is the problem asking for?

Answer 24

whoops. the equation is ax+z=aw-y, solve for a. You add y on both sides giving you ax+z+y=aw. And then I don't know what else to do.

Answer 25

okay this one is more tricky, but do able

Answer 26

first let's look at the a terms here? are alike? no, but what we can do is them on side.

Answer 27

so you can do this ax+z+y=aw take the ax-aw and than take -z-y so you should have the following ax-aw=-z-y

Answer 28

got it?

Answer 29

yes.

Answer 30

this is where it is tricky what can we do with the a's here?

Answer 31

add the 2 a's to get 2a(wx)=-z-y ?

Answer 32

try factoring an a.

Answer 33

did you factor an A?

Answer 34

I don't understand again..

Answer 35

I have it 2a(wx)=-z-y ? from this point take the wx and divide by -z-y so therefore you would 2a=-z-y/wx next divide by 2 to get the a alone so you should have A=-z-y/2wx.

Answer 36

Okay thank you so much! I understand it now! :D

Answer 37

really make sure you understand ask questions plz if something isn't clear?
