Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- 2 axles - [tex]x \le 40000[/tex].
- 3 axles - [tex]x \le 60000[/tex].
- 4 axles - [tex]x \le 80000[/tex].
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e. [tex]\le[/tex]
(a) 2 axles
The maximum weight, here is 40000.
So, the inequality is:
[tex]x \le 40000[/tex]
(b) 3 axles
The maximum weight, here is 60000.
So, the inequality is:
[tex]x \le 60000[/tex]
(c) 4 axles
The maximum weight, here is 80000.
So, the inequality is:
[tex]x \le 80000[/tex]
