The mechanical advantage of the block and tackle is that it is easier to lift a lock using multiple parts of the rope that go around the system of pulleys. If there are no friction, the mechanical advantage is exactly equal to the number of parts of the rope that are attached to the load.
Answer:
-16
Step-by-step explanation:
You don't know the number that 12 is multiplied by, so substitute x for it in the equation. then you get 12x = -192 (it has a product of -192, so you can set up an equation). Then solve for x. Divide both sides by 12, and you get x = -16, thus giving the answer to your question.
