Answer 2

Solving the Problem

To solve the problem, we need to substitute the numbers 7, 8, and 9 into the placeholders and then perform the calculations.

The given placeholders are: - ?, ?, 7-5, ? - Page 16 - ?, ?, 9, 11, 7, 20, 1, 90, 5, 4, 8, ?, ? - 0,7; 1,9; 19,8; 5199,6 - 7, 8, 9, 10 - 1, 2016

Let's substitute the numbers and perform the calculations.

Substituting Numbers

1. ?, ?, 7-5, ? - Substituting 7, 8, and 9: 7, 8, 2, 9

2. Page 16 - No substitution needed.

3. ?, ?, 9, 11, 7, 20, 1, 90, 5, 4, 8, ?, ? - Substituting 7, 8, and 9: 7, 8, 9, 11, 7, 20, 1, 90, 5, 4, 8, 7, 8

4. 0,7; 1,9; 19,8; 5199,6 - No substitution needed.

5. 7, 8, 9, 10 - No substitution needed.

6. 1, 2016 - No substitution needed.

Performing Calculations

1. 7-5 - Result: 2

Conclusion

After substituting the numbers and performing the calculations, we have the following results: - ?, ?, 7-5, ?: 7, 8, 2, 9 - Page 16 - ?, ?, 9, 11, 7, 20, 1, 90, 5, 4, 8, ?, ?: 7, 8, 9, 11, 7, 20, 1, 90, 5, 4, 8, 7, 8 - 0,7; 1,9; 19,8; 5199,6 - 7, 8, 9, 10 - 1, 2016
