Answer:
108 slices
Step-by-step explanation:
One pie is 6 slices so 6*18 is equal to 108
Answer:
A.) x-y=2 and x+2y=-2
Step-by-step explanation:
For option A, we have:
x-y=2
x+2y=-2
Subtract the first equation from the second, to get:
2y--y=-2-2
This implies that:
2y+y=-2-2
Simplify to get:
3y=-4
Divide both sides by 3 to get:

We substitute y=-1.3 into the first equation to get:
x--1.3=2
x+1.3=2
x=2-1.3
x=0.7
The solution is (0.7,-1.3), which is approximately (0.7, -1.4)
By inspection, all the other factors have solutions not close to (0.7, -1.4)
2/15 = 0.1333333333...
It is a repeating decimal, because a terminarog decimal ends, and this doesn't end.
Answer:
The answer is
.
Step-by-step explanation:
This is because when you multiply them together you get
,
,
, and 
When you add the like terms you get,

38 degrees
x+52=90
90-52=36
Therefore, angle 2 equals 36 degrees
