Answer 1

[AI-generated answer — Bot GPT 3.5]

To simplify the expression 2.2 − 0.5(0.6x − 1.8), we can distribute the -0.5 to the terms inside the parentheses:

2.2 - (0.5 * 0.6x - 0.5 * 1.8)

Simplifying further:

2.2 - 0.3x + 0.9

Combining like terms:

(2.2 + 0.9) - 0.3x

2.2 + 0.9 - 0.3x

3.1 - 0.3x

Therefore, the expression is equivalent to 3.1 − 0.3x, which corresponds to response option D.
