If <em>n</em> = 0.151515…, then 100<em>n</em> = 15.151515…
Then
100<em>n</em> - <em>n</em> = 15.151515… - 0.151515…
99<em>n</em> = 15
<em>n</em> = 15/99 = 5/33

Answer:
2/9
Step-by-step explanation:
given that Tyler selects one card from the three(4,5, and a King), and rolls a number cube.
We find that A the event of selecting one card and B getting a number on rolling a number cube are independent events.
No of cards = 3
Prob of selecting 5 from 3 cards = 
When rolling a number cube (assuming fair) there is equally likely for all numbers to appear from 1 to 6
Prob of getting 5 =
Prob of getting less than 5 =
Since these two events are independent,
the probability that she selects the 5, and rolls a number less than 5
= Product of probabilities

Answer:
<u>x=6</u><u> y=16</u>
Step-by-step explanation:
I will use elimination
y=2x+4
y=2x+x-2
*3 y=2x+4 3y=6x+12
*2 y=3x-2 2y=6x-4
3y=6x+12
- 2y=6x. -4
<u>y=16</u>
16=2x+ 4
-4 -4
12= 2x
/2 /2
<u>6=x</u>
