Question

Sabendo que a+b+c=72 e a/b=b/4=c/3, calcule os valores desconhecidos.

Answer 1

A/2 = B/4 --> 4A = 2B --> B = 2A A/2 = C/3 --> 3A = 2C --> C = 3A/2 A + B + C = 72 A + 2A + 3A/2 = 72 2A + 4A + 3A = 144 9A = 144 A = 144/9 A = 16 B = 2A B = 2×16 B = 32 C = 3A/2 C = 3×16/2 C = 24 A = 16 , B = 32, C = 2
