Q. Mariana wears her winter coat when the temperature is colder than

-4^{\circ} \mathrm{C}

.

\newline

Write an inequality that describes

t

, temperatures at which Mariana wears her winter coat.

\newline

+\stackrel{-x}{=}

Temperature Condition: Mariana wears her winter coat when the temperature is colder than $-4$ degrees Celsius. To represent this condition with an inequality, we need to use a less than symbol ( $<$ ) because the temperatures at which she wears the coat are less than $-4$ degrees Celsius.
Inequality Representation: The variable $t$ represents the temperature. Since Mariana wears her coat at temperatures colder than $-4$ degrees Celsius, the inequality will be $t < -4$ .
Checking the Inequality: We should check the inequality to ensure it makes sense in the context of the problem. If $t$ is $-5$ , which is colder than $-4$ , Mariana would wear her coat, and $-5 < -4$ is a true statement. If $t$ is $-3$ , which is warmer than $-4$ , Mariana would not wear her coat, and $-3 < -4$ is a false statement. This confirms that our inequality is correct.
