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

Have an amazing day!

Answer: 2.5

Step-by-step explanation:

What we know:

Both sides need to be equal, and one side already has a constant defined value.

That value is 25 (units)

How to solve:

By using a simple algebraic equation, we can find the value of a triangle's weight. X will represent a square's weight, and y will represent a triangle's weight.

Process:

Set up equation                                                 5x = 2x + 6y

Substitute                                                           5(5) = 2(5) + 6y

Simplify                                                               25 = 10 + 6y

Cancel out                                                         -10    -10

                                                                           15 = 6y

Separate variable                                              /6    /6

Solve                                                                   2.5 = y

Solution: y (triangle weight) = 2.5

You can check this by adding 2.5 6 times (15) to 5 2 times (10). This will equal 25, which would balance out the other side
