    I thought that i would subtract 125 and 52 to get the answer.. but i wasnt so sure that wass right.

    :))!! The map shows the route for a race. You are at A, which is 6000 feet from the first checkpoint B. The second checkpoint C is located at the midpoint between B and the end of the race D. The total race is 3 miles. How far apart are the 2 checkpoints?

    6000 feet = 1.13636 miles (roughly)

    The total length of AD is 3 miles, so 1.13636 + x + x = 3 solve that for x to find the answer

    alternatively, you can convert 3 miles to feet to get 3 miles = 15,840 feet

    then solve 6000 + x + x = 15840 for x to get the answer in feet

    then you have 6,000 + 2x = 15,840.. u -6000 to both sides and get 2x = 9840.. now divide that by 2 and X = 4920

    to convert that to miles (optional in my opinion, but you never know), divide that by 5280

    yes, if you want to convert to miles, but I like the answer in feet (it's a much cleaner number)

    Thanks!!! theres just alot of problems I dont get.. and hate to ask :) But Im glad you like helping.. makes me feel better. Felt like I was askin for to much. Ray GL bisects angle FGM. Suppose angle FGL measures (6x +4)º while angle LGM measures (8x - 4)º. What is the measure of angle FGM?

    you're right (my bad) 6x + 4 = 8x - 4 6x + 4-4 = 8x - 4 -4 6x = 8x - 8 6x-8x = 8x - 8-8x -2x = -8 -2x/(-2) = -8/(-2) x = 4

    so FGM = 14x FGM = 14*4 FGM = 56 So angle FGM is 56 degrees
