Answer:
the commutative property of addition :)
Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11

300+5+20 COULD BE ONE WAY
A co-terminal angle is basically any radian value that you can get by either adding or subtracting a full rotation from the original one.
In this case, you can do 2pi/7 + 2pi, or 2pi/7 - 2pi.
Your answer is either 16pi/7 or -12pi/7. There’s actually an infinite amount of answers you could get, but these two are the easiest to come by.
