Answer:
a. x/y = 2 b) y/x +y =1/3 c) x-y/y= 1 d) y/x = 1/2
Step-by-step explanation:
Solve for
a) x/y
as we know x +y/y = 3
x+y= 3y
x= 3y-y
x= y(3-1)
x/y= 3-1
x/y = 2
b) y/x+y
as we know x +y/y = 3
x+y = 3y
1= 3y/x+y
1/3 = y/x+y
So y/x +y =1/3
C) x-y /y
as we know x +y/y = 3
x +y = 3y
subtracting 2y from both sides
x +y -2y = 3y- 2y
x-y = y
dividing both sides by y
x-y/y = y/y
x-y/y= 1
d) y/x
as we know x +y/y = 3
x +y = 3y
x= 3y- y
x= 2y
dividing both sides by x
x/x = 2y/2x
1 = 2 x (y/x)
1 / 2 = y/x
Or y/x = 1/2
Best of luck.

Answer:
Step-by-step explanation:
Total number of rolls = 50
Number of times rolling a 6 = 8 times
Number of times not rolling a 6 = 50 -8 = 42
P(~6) = 42/50 = 0.84
Answer:
x=13
Step-by-step explanation:
