Answer 1

b

Explanation:

becasue I did and and check with teacher

Answer 2

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Explanation:

Given :

|x – 72.5| = 4.

When the Temperature of x is minimum So the Minimum temperature is

`|x - 72.5| = 4\\it\ can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5`

When the Temperature of x is maximum So the Maximum Temperature is

`|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5`

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °
