Answer:

600 pieces

Step-by-step explanation:

pieces/ time(min) = (395-275) / (22-10) = 120/ 12 = 10

10= x (pieces) / 60(min) => x = 60×10 => x = 600 pieces

What is the justification for the step taken from line 2 to line 3?

stiv31 [10]

Step-by-step explanation:

$3x+9-7x=x+10+x\\-4x+9=2x+10\\-6x+9=10\\$

In the line 2, only variables were operated with a reduction of similar terms in each side of the equation, giving as result -4x at one side, and 2x at the other side.
In the line 3, terms with variables were joined together in one side of the equation, and then, they were operate it, given as result -6X.
