Answer: [tex]t\leq 45[/tex]
Step-by-step explanation:
For this exercise it is important to remember the meaning of the symbols of inequalities. These are:
[tex]<[/tex] means "Less than".
[tex]>[/tex] means "Greater than".
[tex]\leq[/tex] means "Less than or equal to".
[tex]\geq[/tex] means "Greater than or equal to".
Let be "t" the the temperature (in °F) of the refrigerator.
According to the information given in the exercise, the temperature inside the refrigerator is no more than [tex]45\ \°F[/tex].
In other words, the temperature inside the refrigerator is less than or equal to [tex]45\ \°F[/tex].
Knowing this, you can write the following inequality to represent this situation:
[tex]t\leq 45[/tex]
