Answer:
1. 4w = 25
2. w = 6.25 (weight of one circle)
Explanation:
1. Assuming the hanger is well balanced on both sides, where in one side you have 4 equal circles that weigh the same, and in the other side, you have a weight of 25 that balances it.
Thus, the hanger can be represented with the equation below:
4w = 25
2. Weight of one circle, w, can be found by solving for w in the equation that represents the hanger.
Thus:
4w = 25
Divide both sides by 4
4w/4 = 25/4
w = 6.25
