The answer is 62.5

Answer:
4
Step-by-step explanation:
The mean of 2x and 12 is (2x+12)/2, so we get the equation:
(2x+12)/2 = 10 =>
x+6=10
x = 10-6 = 4
* Your question states four numbers, but you write only two... the answer could be wrong because of that.
Answer:
y = x - 9
Step-by-step explanation:
Find the slope of the first line.
(-9 + 5)/(5 + 9)
-1
Lines perpendicular have opposite reciprocal slopes
1
Find the middle point of the first line, this is where it will intersect with the bisector.
5 + - 9/2 = 2
-5 + -9/2 = -7
(2,-7) is the midpoint
Use Point Slope Form to reduce it to Standard Form
y + 7 = 1(x - 2)
y + 7 = x - 2
y = x - 9
Just subtract the -6 from the 42.
