Answer:
MO = 17
Step-by-step explanation:
First, you need to define what if the unknown x. 
segment MN and NO are equal to MO. 
thus, your equation for the combination is x +8
Now set the values equal to each other
x + 8 = 3x - 10 (subtract x from both sides) 
8 = 2x - 10 ( get your x value alone, add 10 to both sides)
18 = 2x (simplfy)
x = 9 
Now plug x value into MO
3 (9) - 10 = 17
Check with opposing equation: 
9 + 8 = 17 √

Answer:
The equation to determine the total length in kilometers is  
The total length in kilometers of Josh’s hike is  38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;

Hence, The equation to determine the total length in kilometers is  
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;

Hence,  The total length in kilometers of Josh’s hike is  38 km.
