Inequalities and their symbols

For each statement about a number \(x\), decide whether \(x=18\) satisfies it. (i) \(x\) is at least \(18\). (ii) \(x\) is more than \(18\). (iii) \(x\) is no more than \(18\). (iv) \(x\) is below \(18\).

State whether each statement is true or false. (i) \(-8>-5\) (ii) \(3\ge3\) (iii) \(-2<0\) (iv) \(\tfrac{1}{4}\le0.2\)
