Answer:
The probability is 0.1 (or 10%)
Step-by-step explanation:
The probability is the ratio of the number of favorable outcomes and the total number of possible outcomes.
The favorable count is determined as follows: we are considering Green marbles. There are 7 of them in the box, so 7 possible picks at the first draw. Since you don't replace the pick, at the next drawing there are only 6 Green ones. So for each of the 7 possible first picks, there are 6 possible second picks: number of possibilities is 7 by 6 = 42.
The total number of possible drawings, irrespective of color is determined as follows: there are 21 marbles in total at first drawing, and 20 at second. So, for each first pick there are 20 possibilities, i.e., total number is 21 by 20 = 420
The probability is therefore:
P = 42 / 420 = 1 / 10 = 0.1 (or 10%)

what i would do first is distribute to get rid of those evil parenthesis and make this all simple ^-^
So, we take 8 times x, and 8 times 4.
Our equation, is now 12 - 2x = 8x + 32
Now, what i would do, is simplify it. Get x to one side, and a whole number to the other. Well, for me it would be easier to keep the larger number on the right, and x on the left!
So we have to be fair, and keep it equal! So, i would start with.... subtracting 32. Since its a positive 32, to cancel it out we have to subtract 32, to get to zero! so, by subtracting 32 on both sides ( 12 - 32 and 32 - 32) we end up with -20 - 2x = 8x
Now looking at - 20 - 2x = 8x, i can see what i need to do. i need to get x to one side, and whole numbers to the other. There are no whole numbers on the right, just variables and coefficients, so i have to get that x away from the left!
So, im going to add 2x on both sides, to eliminate it! So we add 2x on the left to cancel it out, and add 2 x on the right to balance it out! We are now left with -20 = 10x
Now what we do is we get rid of that tag along right by the x! Yep, that little 10 there! He has to go!
How to we get rid of him? Well, he is being multiplied by the x! So, we have to do the opposite and divide to get him alone. So, we divide by 10 on both sides, and we are left with -2 = x!
Now, time to check your answer! Basically, you replace x with -2 in the equation! Here we go:
12 - 2(-2) = 8(-2 + 4)
First we should start with multiplying! when we multiply the -2 in the equation, we get 12 + 4 = 8(2), and we can finish that off by simplifying it to 12 + 4 = 16
when we simplify it and add 12 + 4, we get 16. So we are left with 16 = 16.
This equation is true, so we are right! -2 DOES equal x!

Make the other side x.
12x=42
x=42/12=3.5
The perimeter is 2x+2y where x and y are sides of the rectangle.
P= 2(3.5)+2(12)=7+24=31 inches
Hope this helps.
