Answer 3

To simplify the expression 5(2 - 5x) + 20(x + 0.4) - x, we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's simplify it step by step:

Step 1: Simplify the expressions within parentheses. 5(2 - 5x) becomes 10 - 25x. 20(x + 0.4) becomes 20x + 8.

Now the expression becomes: 10 - 25x + 20x + 8 - x.

Step 2: Combine like terms. -25x + 20x - x can be simplified as -6x. 10 + 8 can be simplified as 18.

The simplified expression is: -6x + 18.
