1) 7,16 - 3, 615=3,545

2) 20,4 ×6,5=132,6

3) 3,8×3,545=13,471

4) 132,6-13,471=119,129

5) 119,129+41,9=161,029

20,4 ×6,5 - 3,8 × ( 7,16 - 3, 615 ) + 41,9=161,029

Answer 2

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

1. First, calculate the expression inside the parentheses: 7.16 - 3.615 = 3.545

2. Next, perform the multiplications:

   • 20.4 × 6.5 = 132.6
   • 3.8 × 3.545 = 13.491

3. Finally, add and subtract to get the result: 132.6 - 13.491 + 41.9 = 160.009

So, the result of the expression 20.4 × 6.5 - 3.8 × (7.16 - 3.615) + 41.9 is approximately 160.009.
