Step-by-step explanation:
T = beads of Ting Ting = 165
S = beads of Sherie.
R = beads of Roxanne.
S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads
R = 1/2 × S = 1/2 × 132 = 66 beads
Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.
Well, y=ny
2(y-1)=ny
(where ny is not-yellow)
You get y=2y-2 or y=2. You had two yellow birds and two other types.
