Wildlife biologists tag deer in wildlife refuges. they originally tagged 240 deer and released them back into refuge. the next month, they observed 180 deer, of which 30 deer were tagged. approximately how many deer are in the refuge? write a proportion and show your work to determine ur answer.

150 deer because if they killed or tagged 30 then it would be 180-30=150

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
