Simone is going snowboarding tomorrow if the temperature is equal to or colder than 5 degree Celsius. Write an inequality that is true only for temperatures (t) at which Simone will go snowboarding.

We know that Simone is going to snowboard tomorrow if the temperature is equal to or colder than 5 degrees Celsius. Equal to or colder basically means less than or equal to. The sign for that is ≤. Since we know that t is less than or equal to 5 degrees Celsius, we can substitute the ≤ sign for less than or equal to, giving us our inequality of t ≤ 5.
