Answer:
2 grams
Step-by-step explanation:
One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore, if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.
t + 4 + 4 = t + t + t + 4
Simplify,
t + 8 = 3t + 4
Inverse operations,
t + 8 = 3t + 4
-4 -4
t + 4 = 3t
-t -t
4 = 2t
/2 /2
2 = t
