The inequality t - 9 < 27 can be simplified as follows:
t < 36
On the number line, we would start at 0 and count up to 36, excluding 36. So the number line should start at 0 and end just before 36, with an open circle indicating that 36 is not included in the solution.
The best representation of this solution is:
[0, 36)
Marcus’s mom lets him play video games for a certain amount of time each day. He has already spent 9 minutes playing video games and has fewer than 27 minutes left to play. The inequality
t – 9 < 27 can be used to determine the number of minutes Marcus has left to play video games.
Which number line best represents the solution to the inequality?
