Answer:
Step-by-step explanation:
140x = 23x - 5 +6x
140x= 23x+6x - 5
140x= 29x - 5
140x-29x=-5
111x = -5
x = -5/111
Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.

Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.
B
B is correct.
C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o
D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.
In logic and mathematics, a truth value, sometimes called a logical value, is a value indicating the relation of a proposition to truth.
