The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours. Daryl plans to be gone for at least 6 hours, and he has a plant outside. If he wants the plant to remain in temperature above - 10°c, should Daryl move his plant to a warmer location before leaving?

An inequality to model the problem is

✔ 20 - 5x > - 10

.

The solution is

✔ x < 6

.

Step-by-step explanation:

no one could find the answer so here it is. u r welcome

The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

Temperature drops by 5°c per hour

So we find the temperature after 6 hours

In 1 hour temperature drops = 5°c

So in 6 hours = 6 * 5 = 30°c

In 6 hours, temperature drops by 30°c

the actual temperature is 20°c. after 6 hours the temperature becomes

20°c - 30°c = - 10°c

So, after 6 hours the temperature will be - 10°c

Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

In 6 hours or more than 6 hours, the temperature will drop less than - 10°c.

So, Daryl should move his plant to a warmer location before leaving
