Answer:
2.5
Step-by-step explanation:
Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5
1: 5 x 5 = 25
2: 5 x 2 = 10
3: 25 - 10 = 15
4: 15/6 = 2.5
The weight of each triangle is 2.5
