Answer:
100 miles
Step-by-step explanation:
We know this because,
lets say they start at 0
0+the first 15 is 15
15+23=38
then when they backtrack 2 miles
you subtract 2
38-2=36
so they have gone 36 miles so far.
to get the amount of miles they have to go you can subtract.
136-36=100
So that is how I got 100.

I could not get it to work with all of those numbers. The only number that caused an issue was 29. I used 28 instead and it worked. I'm not sure if 29 was a typo, but I couldn't get 29 to work.
Answer:
x=14
Step-by-step explanation:
2(3x-4)=5x+6
first get rid of the parentheses by multiplying the 2
6x-8 = 5x+6
put like terms on one side of the equation. Start with the 5x, move it to the left side
(6x-8)-5x = (5x+6)-5x
x-8 = 6
Again, put like terms on one side of the equation. Move the 8 to the right side
(x-8)+8 = 6+8
=> x = 14
B)
4x - 3 = 2(x-1)
Start again by getting rid of the parentheses to make it a clean equation... aka distribute the 2:
4x-3 = 2x - 2
Move the like terms to one side of the equation. Start with x.. move 2x to the left:
(4x-3)-2x = (2x-2)-2x
=> 2x-3 = -2
Move the like terms to one side of the equation.Now move the -3 to the other side:
(2x-3)+3 = -2+3
=> 2x=1
Lastly, divide by 2 on both sides to find out what x is:
(2x)/2=1/2
=> x = 1/2
..so no, Charlie was incorrect.
