Answer- 70
38+x+x+2= 180
Collect like terms
40 +2x=180
Bring 40 to the other side and subtract
2x=140
Divide by 2 to get x alone
X=70
False it is still 50%
of course this assumes an ideal coin. in practice, after many many tosses, a slight preference becomes clear

<u>Because ∆XZW and WYZ is the same height and </u>
<u>Because ∆XZW and WYZ is the same height and the are of ∆WXZ to the the WYZ </u>

<u>Because xy=21</u>
Answer:
y=-2x-7
Step-by-step explanation:
parallel lines have the same slope
our new line so far:
y=-2x+b (b is a place holder)
subsitute (-4,1) into the equation
1=-2(-4)+b
1=8+b
-7=b
new line:
y=-2x-7
X+4=y=-2x-2
x+4=-2x-2
add 2x to both side
3x+4=-2
minus 4 both sides
3x=-6
divide 3
x=-2
sub back
y=x+4
y=-2+4
y=2
(x,y)
(-2,2)
