Answer:

a. x < 55

Step-by-step explanation:

We know that the temperature in November was less than 55° every single day, we are then asked to find which inequality out of the four given shows the temperature in November.

To do so, take the most crucial information, "the temperature in November was less than 55° every single day." The words "less than" makes us know that we will be using the sign "<". Looking at the answers, we see only one that uses it, and that is a.

Therefore a is the correct answer.
