Question

(i) which three of these ages can a person be to set up an account?
13 14 19
(ii) let $x$ be an age, in years.
(iii) write an inequality to represent the ages a person can be to set up an account.
$x$ ? 13

Explanation:

Step1: Identify valid ages

From the options, 13, 14, 19 are all ages that meet the minimum requirement (since 13 is the lowest listed and all are ≥13).

Step2: Formulate the inequality

Since the minimum age to set up an account is 13, the age \(x\) must be greater than or equal to 13.
<Expression>
\(x \geq 13\)
</Expression>

Answer:

1. The three valid ages: 13, 14, 19
2. The inequality: \(x \geq 13\)
