HELP! 1) 12x < 3,6 2) -15x > -45 3) x/4 > -2

Answer 1

1) 12х больше чем 3,6
2) +
3)+

Answer 2

To solve the given inequalities, we'll go through each one step by step:

1. 12x < 3.6: To isolate x, we can divide both sides of the inequality by 12. However, since we're dividing by a positive number, the inequality sign remains the same.

12x < 3.6 x < 3.6/12 x < 0.3

So the solution to the inequality is x < 0.3.

2. -15x > -45: To solve this inequality, we can divide both sides by -15. However, dividing by a negative number reverses the inequality sign.

-15x > -45 x < (-45)/(-15) x < 3

So the solution to the inequality is x < 3.

3. x/4 > -2: To solve this inequality, we can multiply both sides by 4. Since we're multiplying by a positive number, the inequality sign remains the same.

x/4 > -2 4 * (x/4) > 4 * (-2) x > -8

So the solution to the inequality is x > -8.

To summarize the solutions:

1. x < 0.3
2. x < 3
3. x > -8
