Answer:
begin{aligned}
& x = \frac{D_x}{D} = \frac{-616}{-154} = 4 \\
& y = \frac{D_y}{D} = \frac{ 616}{-154} = -4 \\
& z = \frac{D_z}{D} = \frac{-770}{-154} = 5
\end{aligned}
Step-by-step explanation:
For this case we can propose a rule of three:
bottle ------------>
minutes
x --------------------------------------> 1 minute
Where the variable "x" represents the number of bottles that can be filled in 1 minute.
