D=M/V solve for V. I know the answer is m/d but is there any other way to do it besides multiplying V so you would get

Dv=M then you divide by D on both sides but what if you multiply by M to get V by itself so

D=M/V so M/V*M cancels out M snd D*M is Dm=V

Why doesn’t that work?

See below

Step-by-step explanation:

To solve for V, we want to first multiply both sides by V, then divide by D.

        [multiply both sides by V]

     [divide both sides by D]

That is the correct answer.

You cannot multiply both sides by M because that would give you M². The whole point is to want to isolate V. In the case of multiplying, you are actually adding more M to the same side. I will demonstrate what it will look like.

      [multiply both sides by M]

Now, you can multiply both sides by M, and still get the right answer, but that just takes more unnecessary steps. When you say "D=M/V so M/V*M cancels out M snd D*M is Dm=V", that is incorrect. M/V*M DOES NOT cancel out M. It create M² instead.

I hope this answered your question. Let me know if you have anymore questions in the comments.

Both types of lines are built on the same plane although they meet different objectives for which they are built.

Step-by-step explanation:

The difference is that in the case of parallel lines they will never cross and in the case of perpendicular lines if they cross each other, which can give rise to the formation of right angles to each other.
