Suppose that t = x+y/1-xy. Show that when x = 1/a and y = 2a-1/a+2, the value of t does not depend on the value of a.

If angle 2=3x +1 and angle 3=2x +4what is angle 2

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?
