linear inequalities

if $$a>b$$  , which of the following is true

一个不等式组中的两个不等式的解集在数轴上的表示如图所示，则这个不等式组的解集为

what is the solution set same as the diagram

the following system inequalities

$$x\le1$$  

$$x+2<1$$  

what is greatest integer of the solution

if the system inequalities

$$x>2$$  

$$x<m$$   

has no solution, what is the range of m

the solution set of the system inequalities

  $$x>-1$$

  $$x\ge2$$  

$$x<5$$  

is :

solve the inequality

$$\frac{a+2}{2}+\frac{2a-1}{3}\ge\frac{5a+2}{6}+1$$  

the solution set of the inequality

$$\frac{4x-1}{3}-1\ge\frac{1-x}{2}$$  

is

which of the following system inequalities whos solution set is

$$2<x<3$$  

which diagram shows the solution set of the system inequalities

$$x+1\le0$$  

$$2x+3<5$$  

There are three numbers $$a,\ 1+a,\ -a$$  located on the number line from left to right, find the range of "a"
