Answer:
20
Step-by-step explanation:
First, rewrite the numbers in numerical order:
8, 10, 10, 15, 15, 20, 20, 20, 20, 25, 25, 25, 35
Then find the middle number: (note there's 6 numbers on each side of <u>20</u>)
<em>8 10 10 15 15 20 </em><u>20</u> <em>20 20 25 25 25 35</em>

Answer:
not sure what the question is but here are some possible answers
Step-by-step explanation:
cost 63 - sell price 54 = 9 dollars lost per sweater sold
percentage of lose per sweater would be 14%
-4x - 5y = 7
3x + 5y = -14
You can add these two equations together straightaway since the y-terms have opposite coefficients.
-4x - 5y = 7
3x + 5y = -14
+___________
-x - 0 = -7
-x = -7
x = 7
Substitute 7 for x into either of the original equations and solve algebraically to find y.
3x + 5y = -14
3(7) + 5y = -14
21 + 5y = -14
21 = -14 - 5y
35 = -5y
-7 = y
Finally, check work by substituting both x- and y-values into both original equations.
-4x - 5y = 7
-4(7) - 5(-7) = 7
-28 + 35 = 7
7 = 7
3x + 5y = -14
3(7) + 5(-7) = -14
21 - 35 = -14
-14 = -14
Answer:
x = 7 and y = -7; (7, -7).
