A:
Answer: OPTION A.Step-by-step explanation: For this exercise you need to remember the meaning of the inequalities symbols: [tex]<[/tex] → It means "Less than" [tex]>[/tex] → It means "Greater than" [tex]\leq[/tex] → It means "Less than or equal to" [tex]\geq[/tex] → It means "Greater than or equal to" In this case you know that ice cream at [tex]-2\°C[/tex] is cooler than ice cream at [tex]4\°C[/tex]. Since [tex]-2\°C[/tex] is negative, this tempereture is less than the temperature of [tex]4\°C[/tex]. Therefore, you can conclude that the inequality best represents that ice cream at [tex]-2\°C[/tex] is cooler than ice cream at [tex]4\°C[/tex] is: [tex]-2\°C<4\°C[/tex]
