**Jasmine**, Wednesday, April 27, 2011 at 4:21pm30=12d, this means 30 is equal to 12*?

You have to find the missing variable, so d would equal 2.5, or 2 1/2

Divide both sides by the co-efficient.

12/12 leaves you with d.

30/12 leaves you with 2.5

D=2.5

Check your work.

30= 12*2.5

12*2.5= 30

30=30
