Answer:

x = 0

Step-by-step explanation:

-3x - 3(6x - 1) = 3(1 - 5x)

Distribute

-3x -18x +3 = 3 -15x

Combine like terms

-21x +3 = 3 -15x

Add 21x to each side

-21x +21x+3 = 3 -15x+21x

3 = 3+6x

Subtract 3 from each side

3-3 = 3-3+6x

0 = 6x

Divide by 6

0/6 = 6x/6

0= x

IRINA_888 [86]
You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is 
4/52 on the first draw.

For the second draw the probability is the same.
4/52

The probability for both happening is 
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597
