Among the provided statements, the true ones are: 6, 7, 8, 9, 10, and 12. These statements hold valid mathematical relationships, while others are false.
Sure, let's represent the analysis in plain text:
Let's analyze each statement to determine whether it is true or false:
1. 5.2 = 2.5 - False
2. 6 * 3.5 = (6 * 3) * 5 - False
3. If x = y and y = 7, then x = 7 - True
4. 8 = 8 - True
5. 1/2.2 = 1 - False
6. 8.1 = 8 - False
7. If x = y, then y = x - True
8. 4 * (8 + 1) = 4 * 8 + 4 * 1 - True
9. 10 + (3 + 2) = (10 + 3) + 2 - True
10. 6 + 2 = 2 + 6 - True
11. 5.0 = 0 - False
12. 6 + 0 = 6 - True
In summary:
- True statements: 6, 7, 8, 9, 10, 12
- False statements: 1, 2, 3, 5, 6, 11
The correct answer is: 6, 7, 8, 9, 10, 12.
