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