Answer:
first line is mode second line is 21
Remove parenthesis on m-2 because you don't need to distribute ( you have an invisible 1, but it won't change the values bc it's a one) Combine your like terms on the side you removed the parenthesis. m-2-5 -> m-7. Now on the other side distribute the 2 to the terms in the parenthesis. once you've done that your equation should look like this 8- 2m +8. now lets look at th full equation. m-7=8-2m+8 move the -2m to the other side, by adding. you now have an equation like this 3m- 7=16. move the -7 to the other side by adding. 3m=23. divide 23 by 3. you're answer should be m= 23/3
its best to leave your answer as a fraction.
Hope this helped. (:

Step-by-step explanation:
we know that
The sum of interior angles in a triangle must be equal to 180 degrees
so

solve for x





-48 is the answer to the question
mean = Summation of Data/Number of Data Added
mean = [(-54)+(-32)+(-70)+(-25)+(-65)+(-42)] / 6
mean = -288 / 6
mean = -48
