There are two solutions
AG =BG
mesDBG = mesEBG
You would first put 168 over 4 and simplify to get 42 over 1. Then you would divide 504 by 42 to get 12. You would have to drive 12 hours to get 504 miles.
$68.82
$68.82 - $5.32
$63.50 - $3.00
$60.50 / 2
$30.25 each pair of shoes
Event 4 (impossible), Event 3 (probability is 7/20), Event 1 (probability is 6/12 which is greater than 7/20), and Event 2 (certain to happen)
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
