4)422

Answer 3

Let's solve this expression step by step:

1. Start with the parentheses:

   • Inside the first set of parentheses: 5 + 2 = 7
   • Inside the second set of parentheses: 30 + 400 - 8 = 422

2. Now, rewrite the expression with the simplified parentheses: (6.4) - 20(4.8) - 5(7) - 60(422)

3. Perform the multiplications:

   • 20(4.8) = 96
   • 5(7) = 35
   • 60(422) = 25320

4. Rewrite the expression with the simplified multiplications: 6.4 - 96 - 35 - 25320

5. Finally, perform the subtractions: 6.4 - 96 - 35 - 25320 = -25244.6

So, the value of the expression is approximately -25244.6.
