The average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.
To A) write an expression that represents the average change in temperature each minute, and B) if Edgar repeats the experiment and finds the average change in temperature each minute is 1 ° F greater in the second trial than in the first trial, to determine what is the average change in temperature each minute in the second trial of the experiment, the following calculations must be performed:
A)
(-2 x 4 + -3 x 3 + 6) / 10 = X
(-8 + -9 + 6) / 10 = X
-11 / 10 = X
-1.1 = X
B)
(-3 x 4 + -4 x 3 + 7) / 10 = X
(-12 + -12 + 7) / 10 = X
-17/10 = X
-1.7 = X
Therefore, the average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.

Answer: 
Step-by-step explanation:
Let be "x" the price in dollars of one copy of the city newspaper.
You need to analize the information provided in the exercise:
1. The total number of copies of the city newspaper sold in the newspaper stand is:

2. The amount of money earned by selling 1,000 copies of the city newspaper is:

Then, you can determine that the value of "x" can be found with:

3. Finally, substituting values, you get:

Sarah's 10 years old.
Antonio's 2 years old.
2 x 2 = 4
10 x 3 = 30
4 + 30 = 34
2 x 5 = 10
Answer:
xy < 60
Where x is the amount of subscription per month and y is the number of months
Step-by-step explanation:
Given Anna wants to spend less than $60 for the subscription
Let the amount of subscription per month be x
Let the number of months which Anna can enjoy her music be y
The total amount of money spent by Anna on subscription = ( The amount of subscription per month )( Number of months )
Total amount = xy
Given total amount < 60
So xy < 60
Therefore the above is the inequality recquired.
