Question

7 from unit 4, lesson 1 jada has a sleeping bag that is rated for 30° f. this means that if the temperature outside is at least 30° f, jada will be able to stay warm in her sleeping bag. a. write an inequality that represents the outdoor temperature at which jada will be able to stay warm in her sleeping bag. b. write an inequality that represents the outdoor temperature at which a thicker or warmer sleeping bag would be needed to keep jada warm. algebra 1

Explanation:

Step1: Define variable

Let $t$ be the outdoor temperature.

Step2: Analyze part a

Since Jada stays warm when temperature is at least 30°F, we use $\geq$. So $t\geq30$.

Step3: Analyze part b

A thicker sleeping - bag is needed when temperature is less than 30°F. So $t < 30$.

Answer:

a. $t\geq30$
b. $t < 30$
