Because you are not adding the x's .When you add the coefficients, the variable comes along with it.

Because you are adding an amount of the same variable. They are like terms so you would combine them. If it was 10xxx it would be 10+3x. But, 5x+3x+2x is 10 because 3x+2x is 5 and 5x+5x is 10x. You do not add the actual x's together, just the amount that is shown.
Think of it as this way:
5x = x x x x x
3x = x x x
2x = x x
in total, there are 10 x's

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required of the question is not stated.

However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.

Represent the distance from Atlanta to Colleyville with AC

Represent the distance from Atlanta to Bayville with AB

Represent the distance from Bayville to Colleyville with BC

So, we have that:

$AC = 25.5\ miles$

$AB = 10\frac{2}{3}\ miles$

The relationship between AB, AC and BC is:

$AC = AB + BC$

Make BC the subject of formula:

$BC = AC - AB$

$BC = 25.5 - 10\frac{2}{3}$

Convert fraction to decimal

$BC = 25.5 - 10.7$

$BC = 14.8$

Hence, the distance from Bayville to Colleyville is 14.8 miles

At the 3/4 marker, the rider can collect a green ribbon and a blue ribbon.

Because 3/4 is the 3rd stop for a blue ribbon and 3/4 is the 6th stop for a green ribbon.
