Question

1. Match each inequality to the meaning of a symbol within it.

Answer 1

Step-by-step explanation

The symbols we use for inequalities are <, >, ≤ and ≥. The last two are the combination of the first two and the equal symbol.

Inequalities are usually read from left to right, so the meaning of the symbols are

• a ,<, b → a is ,less than, b

,

• a ,>, b → a is ,greater than, b

,

• a ,≤, b → a is ,less than or equal to, b

,

• a ,≥, b → a is ,greater than or equal to, b

Hence, in these three inequalities we have:

• h ,>, 50 → h is ,greater than, 50

,

• h ,≤, 20 → h is ,less than or equal to, 20

,

• 30 ,≥, h → 30 is ,greater than or equal to, h
