59. The total weight of three tables is 16.9 pounds. The first table is twice
as heavy as the second table. The weight of the third table is the
weight of the second table. What is the weight of the first table?

Respuesta :

Answer:

3.38

Step-by-step explanation:

x + y + z = 16.9

x = 2y

y = z

y=y

2y (x) + y(y) + y(z) = 16.0

5y = 16.9

y = 3.38
