Write and solve the number sentences she could use.

Ms. Cloudcover, the TV weatherperson, noted that Sunday’s temperature was 12, much warmer than the -7 on Friday and the -2 on Saturday. She remembered that Thursday’s temperature was 0 and checked to see how far Saturday’s temperature had fallen from Thursday’s temperature. She made a
note to report the average temperature for the 3-day weekend
and the temperature change from Friday to Saturday and from
Saturday to Sunday. Then she began work on a report about
how the high temperatures for each day of the past week had been over or under the normal high temperature for that day.
She wrote,
Sun: -8
Mon: -5
Tues: -2
Wed: 6
Thurs: 3
Fri: -4
Sat: 9
She wondered whether the net effect of the week was more or less than normal. Before she left for the day, she noted that today’s low temperature was and figured the difference between it and the record low of for today’s date

To solve the number sentences, we need to understand the information given and perform the necessary calculations. Let's go step by step:

1. Ms. Cloudcover noted the temperatures for each day of the week. These are the values provided:

Sun: -8
Mon: -5
Tues: -2
Wed: 6
Thurs: 3
Fri: -4
Sat: 9

2. To find the average temperature for the 3-day weekend (Saturday, Sunday, and Monday), we can add up the temperatures and divide by 3:

Average temperature = (9 + (-8) + (-5)) / 3

Calculating this, we get:

Average temperature = -4/3

Therefore, the average temperature for the 3-day weekend is -4/3.

3. Ms. Cloudcover also wants to know the temperature change from Friday to Saturday and from Saturday to Sunday.

Temperature change from Friday to Saturday = Saturday's temperature - Friday's temperature

Temperature change from Saturday to Sunday = Sunday's temperature - Saturday's temperature

Plugging in the values:

Temperature change from Friday to Saturday = 9 - (-4)
Temperature change from Saturday to Sunday = -8 - 9

Calculating these, we get:

Temperature change from Friday to Saturday = 13
Temperature change from Saturday to Sunday = -17

Therefore, the temperature change from Friday to Saturday is 13, and the temperature change from Saturday to Sunday is -17.

4. Finally, Ms. Cloudcover wants to find the difference between today's low temperature and the record low for today's date. However, you haven't provided the actual values for today's low temperature and the record low, so I'm unable to solve this part of the question.

Please provide the values for today's low temperature and the record low in order to calculate the difference between them.

I hope this explanation helps you understand how to approach and solve the number sentences.
