(5,884+5,96•20,5):3,2-30,144

Let's solve the expression step by step.

We have:

\[ (5,884 + 5,96 \cdot 20,5):3,2 - 30,144 \]

1. Calculate \( 5,96 \cdot 20,5 \): \[ 5,96 \cdot 20,5 = 122,78 \]

2. Now substitute this value back into the expression: \[ (5,884 + 122,78):3,2 - 30,144 \]

3. Next, calculate \( 5,884 + 122,78 \): \[ 5,884 + 122,78 = 128,664 \]

4. Substitute this back into the expression to get: \[ 128,664:3,2 - 30,144 \]

5. Now, divide \( 128,664 \) by \( 3,2 \): \[ 128,664:3,2 = 40,20875 \]

6. Finally, subtract \( 30,144 \) from \( 40,20875 \): \[ 40,20875 - 30,144 = 10,06475 \]

Thus, the final answer is approximately: \[ \boxed{10,06475} \]
