Hello there! Given the temperature at 6am in Durango, Colorado was -8° Fahrenheit:
-8° + 15° = temperature at 2pm
• When adding a positive to a negative, we are subtracting the numbers and taking the sign of the greater number. The equation is represented as so:
(-) + (+) = (+)
The general rule corresponding to this equation is that the answer acquires the sign of the greater number. In this case, because 15 is greater than 8, our answer will be a positive number.
-8 + 15 = 7
From 6am to 2pm, the temperature would have risen from -8° Fahrenheit to 7° Fahrenheit. If you need any extra help, let me know and I will gladly assist you.

Answer:
A. 18.4
Step-by-step explanation:
The mean is the average. In order to find the answer you must add all the values of the variables and divide them by the number of variables. Simply just add 14, 15, 18, 20, and 25, and then divide it by 5 (the number of variables). Then you get your answer.
14+15+18+20+25=92
92/5=18.4
A. 18.4

Claire's time to mow all the lawns last week was 1.4 times longer than this week.
<em><u>Explanation</u></em>
Claire mowed each lawn in 
hour last week.
So, the <u>total time taken to mow all 4 lawns last week</u> 
hours.
She mowed the same lawns this week and took 
hour for each.
So, the <u>total time taken to mow all 4 lawns this week</u> 
hours.
Now.....
<u><em>(Total time in last week / Total time in this week)</em></u><em> </em>
So, Claire's time to mow all the lawns last week was 1.4 times longer than this week.
