A120 pound weight is placed 5 feet from the fulcrum. how far from the fulcrum should an 80 pound weight be placed to balance the lever?
answer

Okay i'll help but i dont wanna just spoon feed you it so
do you understand the Topic on : Moments of a Force ?
this question is the easiest form in the topic so you will the main formula
Force x distance from the fulcrum/pivot.(known as a moment of a force)
as the anticlockwise moments = clockwise moments
substitute in the values and work for the distance

im sure u can do it from here :) gl

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
