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

\square

Identify Temperature Range: Mariana wears her winter coat when the temperature is colder than $-4$ degrees Celsius. To write an inequality for the temperatures $(t)$ at which she wears her coat, we need to express ＂colder than $-4$ degrees Celsius＂ in mathematical terms.
Express in Inequality: The phrase ＂colder than $-4$ degrees Celsius＂ means that the temperature is less than $-4$ . Therefore, the inequality will show that the temperature $t$ is less than $-4$ .
Interpret Inequality: The inequality that represents this situation is $t < -4$ . This means that for any temperature $t$ that is less than $-4$ degrees Celsius, Mariana will wear her winter coat.
