Answer 2

It seems like you have a series of equations with missing numbers represented by dashes. Let's solve them step by step:

1. 12-__ = 13-9.4 + 7 To find the missing number, let's first solve the right side of the equation: 13 - 9.4 + 7 = 10.6 + 7 = 17.6

So the equation becomes: 12 - __ = 17.6

To find the missing number, subtract 17.6 from 12: 12 - 17.6 = -5.6

The missing number is -5.6.

2. 6 + __ = -7 To find the missing number, subtract 6 from -7: -7 - 6 = -13

The missing number is -13.

3. 15 - 8, __ - 9 = 15 To find the missing number, add 8 to 15 and then add 9 to the result: 15 + 8 + 9 = 32

So the equation becomes: 15 - 8, __ - 9 = 32

Now, we have a comma between two numbers (15 - 8 and __ - 9), so the missing number is the difference between these two numbers: __ = 32 - (15 - 8) - 9 __ = 32 - 7 - 9 __ = 16

The missing number is 16.

Putting it all together, the completed equations are:

1. 12 - (-5.6) = 17.6
2. 6 + (-13) = -7
3. 15 - 8, 16 - 9 = 15
