Step-by-step explanation:
1) A number <em>m</em> is at least four
 <em>m ≥ 4  ['at least' = ≥ symbol]</em>
<em />
2) 4x  ≤ 20x; x=2
4(2) ≤ 20(2)
8 ≤ 40 
[Im not sure if this is a solution or and inequality :/ ]
3)  x < 5
--> On the line, draw the number 0, and the number five. 'x < 5' also means 'x is less that five.' So, draw a dot over the line before 5, and make an arrow going to the left of the page,
<-----------------------------------o   5
<---|---|---|---|---|---|---|---|---|---|---|---|---|---|--->
                           0
Hopefully this helps! :)
