The speed limit sign on the expressway says that the speed limit is 55 mph. Write an inequality that represents all speeds you can legally drive on the expressway.

Answer 1

The speed limit sign indicates that the maximum allowed speed is 55 mph. Therefore, the speeds you can legally drive on the expressway must be less than or equal to 55 mph.

The inequality representing all speeds you can legally drive on the expressway is:

\[ s \leq 55 \]

where \( s \) represents your speed in miles per hour.

Answer 2

we are using x as the variable

Answer 3

Sure! If you're using \( x \) as the variable, the inequality representing all speeds you can legally drive on the expressway is:

\[ x \leq 55 \]

where \( x \) represents your speed in miles per hour.
