Question

Manuel exercises at least 45 minutes per day. Let 't' represent Manuel's amount of exercise (in minutes per day).

Which of the following equations represents Manuel's exercise time?
a) t = 45
b) t ≥ 45
c) t < 45
d) t > 45

Answer 1

The equation that represents Manuel's exercise time is t ≥ 45, meaning that the value of t must be greater than or equal to 45.

Step-by-step explanation:

The equation that represents Manuel's exercise time is t ≥ 45. This equation means that the value of t, which represents the amount of exercise in minutes per day, must be greater than or equal to 45. Since Manuel exercises at least 45 minutes per day, this equation accurately represents his exercise time. It is important to note that the equation t = 45 would not be correct since Manuel exercises for at least 45 minutes, not exactly 45 minutes.
