In a certain town the temperature, x in degrees Celsius on a certain day is described by two statements:

If 3 times the temperature is increased by 2, the temperature is still less than 14°C.
Twice the temperature minus 7 is greater than -11°C.

Part A: Create a compound inequality to represent the temperature range. (3 points)

He's really smart.

anonymous · Answer

Well @johnweldon1993  could you help ?

johnweldon1993 · Answer

Everything is correct..

Since the want the temperature range...it would be "and"     if we had "or" that means for example we would never be able to reach a certain temp in that range...when we can...

You are correct @Lanayy :)
