Answer 3

Значение выражения:

1) 16 - 29 + 14 - 48: To find the value of this expression, we need to perform the operations in the given order. Let's calculate it step by step: 16 - 29 = -13 -13 + 14 = 1 1 - 48 = -47

Therefore, the value of the expression 16 - 29 + 14 - 48 is -47.

2) -3.2 - 7.8 - 5.4 + 4.6: Similarly, let's calculate this expression step by step: -3.2 - 7.8 = -11 -11 - 5.4 = -16.4 -16.4 + 4.6 = -11.8

So, the value of the expression -3.2 - 7.8 - 5.4 + 4.6 is -11.8.

3) -4.28 - 1.53 - (-7.85) + (-9.06): To simplify this expression, we need to remember that subtracting a negative number is the same as adding a positive number. Let's calculate it step by step: -4.28 - 1.53 = -5.81 -5.81 - (-7.85) = -5.81 + 7.85 = 2.04 2.04 + (-9.06) = -7.02

Therefore, the value of the expression -4.28 - 1.53 - (-7.85) + (-9.06) is -7.02.
