Answer:
x = 19
Step-by-step explanation:
These are vertical angles, which means that the angle measurements are going to be the same. Set the two angle measurements equal to each other:
3x - 3 = 6(x - 10)
Simplify. First, distribute 6 to all terms within the parenthesis:
3x - 3 = 6(x - 10)
3x - 3 = 6(x) - 6(10)
3x - 3 = 6x - 60
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3 and subtract 6x from both sides:
3x (-6x) - 3 (+3) = 6x (-6x) - 60 (+3)
3x - 6x = -60 + 3
-3x = -57
Isolate the variable, x. Divide -3 from both sides:
(-3x)/-3 = (-57)/-3
x = -57/-3 = 57/3 = 19
x = 19 is your answer.

Step-by-step explanation:
Replacement means the probability of each trial is the same (the trials are independent).
For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.
There are 4 queens, so the probability on the first draw is 4/52.
You then replace the queen, so there are still 4 queens in the deck. So the probability on the second draw is still 4/52.
The total probability is the product: 4/52 × 4/52 = 1/169
If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.
