After arranging the data from least to greatest:
Q1: 12.5
Q3: 16
IQR ( Q3-Q1) : 3.5
In order to use the elimination method<span>, you have to create variables that have the same coefficient—then you </span>can eliminate<span> them. Multiply the top </span>equation<span> by 5. Next add the </span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x.</span>
Answer:
Step-by-step explanation:
A(x1,y1) B(x2,y2)
M(x,y) => x=
and y=

-16 + 3n = -(8 + 5n)
The - sign outside the parentheses acts as a -1, and so it is distributed to each term in the parentheses.
-16 + 3n = -8 - 5n
+16
3n = 8 - 5n
+5n
8n = 8
/8
n = 1
