The temperaturestayed above - 15.

x + > = -15

Right?

why the "+"?

x > -15

because it stayed above, meaning greater than.

Ok I wasn't sure. Thank you.

Not quite. To express the statement "the temperature stayed above -15," you would use the inequality symbol for "greater than," which is simply ">", rather than the combination of "+" and ">". Therefore, the correct inequality to represent the statement would be:

x > -15

This inequality states that the value of x is greater than -15, meaning that the temperature is above -15.
