Question

Here is a balanced hanger diagram.

If a square weighs 12 grams and a circle weighs 9
grams, what does a triangle weigh?
4 grams
2 grams
5 grams
3 grams

Answer 1

3=x

Explanation:

12+12+x=24+x

9+9+x+x+x=18+3x

24+x=18+3x

24-18=6

6+x=3x

3x-x=2x

6=2x

6÷2=3 2x÷2=x

3=x

Answer 2

The answer is 3

For the side one you would do 12+12=24+
Go the the other side it would be 9+9=18+3
You could try inserting all those numbers for triangle if you want to do it that way. Any way you do it though you should get 3.
