Answer:
y = 120º
Step-by-step explanation:
180 - (33 + 87) = 60
x = 60
180 - 60 = 120
y = 120º
or y = 33 + 87, because the outer angle of one angle equals the other two inner angles.
Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.

Let the empty side equal zero.
Add 3/d-4 and 2/d+2

Then add that to -3d.

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
I think the independent variable is the number of people and the dependent is the wait time. I see it as the wait time DEPENDS on how many people are in line. This one is kinda confusing tho
Answer:
As in the other problem with the same logic: 46 pies divided for 9 people=8 ppl • 5 pies and 1 person • 6 pies
40+6= 46
The correct option is D.
