Answer:
z = 44º
Step-by-step explanation:
180 - (44+52) = 180 - 96 = 84º
180 - 84 = 96º

180 - 136 = z
z = 44
Both are true, since the organization of the elements doesn't change the set:
So {A} = {B}
Answer:
Step-by-step explanation:
you do this by swapping x and y values
so it becomes x = y/(y+7)
cross-multiply to get
x(y+7) = y
xy + 7x = y
xy - y = -7x
y(x-1) = -7x
y = -7x/(x-1)
y =
