AlgebraEasyInequality for a minimum height
Algebra practice question
A ride requires riders to be at least 120 centimetres tall. If h is a rider's height in centimetres, which inequality must h satisfy?
- A. h ≥ 120Correct
- B. h > 120
- C. h ≤ 120
- D. h < 120
Answer: A. h ≥ 120
"At least 120" includes 120 itself: h ≥ 120.
Why the other answers are wrong
- B. h > 120
- h > 120 would exclude a rider who is exactly 120 cm.
- C. h ≤ 120
- This describes riders who are too short.
- D. h < 120
- This describes riders who are too short.
