Question

The equation r= u/st is equivalent to u = rst.
True or False.
And please explain.

Answer 1

Well let's look at r = u/st

Looks like they are wanting to solve for u. Do you know how to start solving for u?

Answer 2

I know you divide by SOMETHING...

Answer 3

No, since you are dividing you must multiply :) Does the problem look like this?

Answer 4

Oooohhh. Yes, it does.

Answer 5

Yeah, ok. We still mutliply. What do we multiply on both sides of the equation to get u alone on one side of the equal sign? r? u? st?

Answer 6

You can multiply them by st and that isolates u so... then you have u=rst. So the answer is true. Thanks so much! :3

Answer 7

:) No problem! Seems like you understood it very well

Answer 8

I guess so. :D
