ANSWER
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
