The total age for Amelia, Bernard, and Cindy is 10w years. Amelia is 2w years old. Bernard is as old as Cindy.
Express Cindy's age in terms of w. If w = 4, how old is Cindy?
Amelia + Bernard + Cindy = 10w {the total of their ages is 10w}
2w + ? + ? = 10w {Amelia is 2w years old, Bernard and Cindy are the same} ? + ? = 8w {subtracted 2w from each side} 2? = 8w {added ? and ?} ? = 4w {divided each side by 2} Cindy is 4w If w = 4, 4w = 4(4) {substituted 4 in for w} = 16 {multiplied} If w = 4, then Cindy is 16 Ask Algebra House Comments are closed.
