Question

Решите неравенства: а) 1/3х>4 б) 2-5х меньше или равно 0 в) 2(х-1) >3(2-х) помогите, пожалуйста, очень срочно ​

Answer 1

Ответ:

A) 1/3x<4

b)2-5x=0

v)2(x-1)>3(2-x)

Answer 2

а) 1/3х > 4

To solve this inequality, we can multiply both sides of the inequality by 3 to eliminate the fraction:

1/3 * 3x > 4 * 3

x > 12

Therefore, the solution to the inequality 1/3x > 4 is x > 12.

б) 2 - 5х <= 0

To solve this inequality, we can isolate the variable x by moving the constant term to the other side of the inequality:

2 <= 5х

Next, we can divide both sides of the inequality by 5 to solve for x:

2/5 <= х

Therefore, the solution to the inequality 2 - 5х <= 0 is x >= 2/5.

в) 2(х-1) > 3(2-х)

To solve this inequality, we can simplify both sides of the inequality:

2x - 2 > 6 - 3x

Next, we can combine like terms:

2x + 3x > 6 + 2

5x > 8

Finally, we can solve for x by dividing both sides of the inequality by 5:

x > 8/5

Therefore, the solution to the inequality 2(х-1) > 3(2-х) is x > 8/5.

I hope this helps! Let me know if you have any further questions.
