38.73

Step-by-step explanation:

For adding negatives, you basically just subtract. For example, -3+5. To find the answer, you subtract 3 from 5, leaving you with 2. For decimals, you add like normal, but you carry the decimal down, and leave it in the same place.

69.77

Step-by-step

1. Put the numbers in a vertical column, aligning the decimal points

2. Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left.

3. Place the decimal point in the answer directly below the decimal points in the terms.
