Answer 2

Ответ:

$3.3x - 1.6 + 1.2x \leqslant 9.3 +3.5 - 5x \\ 4.5x - 1.6 \leqslant 12.8 - 5x \\ 9.5x \leqslant 14.4 \\ x \leqslant \frac{144}{95}$

x принадлежит {-∞; 144/95}

Answer 3

To solve the inequality $3.3x - 0.4(4 - 3x) \leq 9.3 + 5(0.7 - x)$, follow these steps:

1. Distribute the constants and simplify both sides of the inequality: $3.3x - 1.6 + 1.2x \leq 9.3 + 3.5 - 5x$

2. Combine like terms on both sides: $4.5x - 1.6 \leq 12.8 - 5x$

3. Add 5x to both sides of the inequality to isolate the x terms on one side: $4.5x + 5x - 1.6 \leq 12.8$

4. Combine the x terms: $9.5x - 1.6 \leq 12.8$

5. Add 1.6 to both sides to isolate the 9.5x term: $9.5x \leq 12.8 + 1.6$ $9.5x \leq 14.4$

6. Finally, divide both sides by 9.5 to solve for x: $x \leq \frac{14.4}{9.5}$ $x \leq 1.52$

So the solution to the inequality is $x \leq 1.52$.
