Question

Abc/4r, solve for r

Answer 1

This isn't an equation. So you cant really solve for anything.

Answer 2

The question said to solve the formula

Answer 3

There's nothing to solve unless there's an equal sign somewhere.

Answer 4

For example, 123x :solve for x

There's nothing I can do there.

Answer 5

Sorry it says A= abc/4r, solve for r

Answer 6

That's better. So first step is first. There is a denominator with 4r in it. Because there's a denominator there, we need to multiply both sides of the equation by 4r.

Answer 7

After that step what's next

Answer 8

Tell me where you are at right now.

Answer 9

4r(a) = 4r(abc/4r)

Answer 10

See on the right side, you are dividing by 4r and multiplying by 4r. Anything divided by itself is 1 so it just cancels out.

Answer 11

So we should get 4ra=abc

Answer 12

So now I will have 4r(a) =abc. What's next step?

Answer 13

Well. We want r.

So we need to get rid of everything else on the left side. Because we are dividing r by 4 and a, we should divide by 4a on both sides.

Answer 14

Ok so you get r= abc/4a. Correct?

Answer 15

Correct. But there is another step there.

Answer 16

Look at the right side ad see what we can cancel out there.

Answer 17

A?

Answer 18

Yes. Because you have a in the numerator and denominator you can cancel it out.

Tell me what you get.

Answer 19

R= bc/4

Answer 20

Yes.

Answer 21

Great thanks. I'm trying to figure this out.
One more please
P/q = r/s solve for s

Answer 22

Tell me what steps you would take here to solve this one. It is pretty similar to the other one.

Answer 23

Would you try to find a common denominator?

Answer 24

We need to get S on a side by itself. But it is in the denominator. By multiplying by s on both sides, we get it out of the denominator.

Answer 25

Look like I have sp/q = r

Answer 26

Yes. and now.... you can multiply by what on both sides

Hint: denominator.

Answer 27

Q

Answer 28

Multiple both sides by Q. Then you get sp= rq
Then divide both sides by p and you get s= rq/p. is that correct?

Answer 29

Yes! Congratulations!

You have come closer to algebra mastery.

Thanks for the help
