Answer 3

To evaluate the given expressions, let's perform the calculations step by step:

1. -34 + 17 + (-16): Start by adding -34 and 17, then subtract 16 from the result: -34 + 17 = -17 -17 + (-16) = -33 So, -34 + 17 + (-16) equals -33.

2. 2.3 + (-19) + 3.4: Add 2.3 and 3.4, then subtract 19 from the result: 2.3 + 3.4 = 5.7 5.7 + (-19) = -13.3 So, 2.3 + (-19) + 3.4 equals -13.3.

3. -11.8 + (-20) + (-7): Start by adding -11.8 and -20, then add -7 to the result: -11.8 + (-20) = -31.8 -31.8 + (-7) = -38.8 So, -11.8 + (-20) + (-7) equals -38.8.
