Please help me also with this problem, thanks.

Quiana had some beads. The ratio of the number of black beads to the number of white beads was 1:5. After she added 2 more than twice the number of black beads, she still had 18 fewer black beads than white beads. How many black beads and how many white beads did Quiana have to begin with?

  1. Scott

    w = 5b

    b + 2b + 2 + 18 = 5b

  2. zar

    if this is the equation, I will simplify this as:

    2+18=5b-3b
    20=2b
    20/2 =b
    b=10

    white beads is 20
    black beads is 10
