30 = 12d

  • 7th grade math -

    d = 30/12 = 15/6 = 5/2 = 2 1/2

  • 7th grade math -

    check 12*2 + 6 = 24+6 = 30 sure enough

    The answer to 30=12d


  • 7th grade math -

    30=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

  • 7th grade math -


    Divide both sides by the co-efficient.
    12/12 leaves you with d.
    30/12 leaves you with 2.5

    Check your work.
    30= 12*2.5
    12*2.5= 30

    simplify 6 12/18
