c
Step-by-step explanation:
10×4,000=40,000 because all u do is add an extra zero everything you multiple something by ten
The answer to this question would be: 85/99
In this question, Suzan is taking 8 marble from a bag containing 4 red marbles, 4 green ones, 2 white ones, and 2 purple ones. The total marble in the bag should be: 4+4+2+2= 12. The question is how much the probability to get <4 red marble. In this question, the green, white and purple is not specified so you can join them into not red group. It will be easier to find the probability of "have all the red one" which mean Suzan take 4 red marble and 4 not-red marble<span>
Ways to take 8 marble out of 12=12C5= 12!/4!8!= </span>495
Ways to take 4 red marble out of 4= 4C4= 1
Ways to take 4 not red marble out of 8= 8C4= 8!/4!4!= 70
Probability to <span>have all the red ones= 1*70/495= 14/99
</span>Then the probability does not have all the red ones= 99/99 - 14/99= 85/99
Answer:

Step-by-step explanation:
You want x alone on the left side.
x is being multiplied by 3 and by c.
The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.
You must do the same operation to both sides of an equation, so divide both sides by 3c.

Divide both sides by 3c.

Simplify both sides.
