Question
Write an inequality to represent the following:
Only children of four and under are allowed to play with the equipment.
Let x represent the age of the children allowed on the equipment.
- x > 4
- x ≥ 4
- x < 4
- x ≤ 4
Hint:
We are given a statement. We have to write the expression of inequality for the given statement. We have to see the limits given for the required value.
The correct answer is: x ≤ 4
The given statement is as follows:
Only children of four and under are allowed to play with the equipment.
The variable x represents the age of children allowed on the equipment.
Only children of four and under are allowed on the equipment means, 4 is the maximum limit of the age allowed. The children can have age less than 4 or 4. But, age more than 4 is not acceptable.
So, the variable x can be less than or equal to 4
The sign for less than or equal to 4 is “≤4”
The mathematical representation of the inequality is as follows:
x ≤ 4
This is the given inequality.
For such questions, we have to be careful about the limits.
