y=5/3x-6/8 First, multiply by LCD 24:
24y = 40x -18
40x - 24y = 18
Division by 2 is recommended (this is because 6/8 should have been reduced to 24, making LCD just 12):
20x - 12y = 9
Step-by-step explanation:
He / she didn’t drop down the 2 after subtracting 19 from 242, instead he / she dropped down a 0.
In this question, Suzan is taking 5 marble from a bag containing 4 red marbles, 3 green ones, 4 white ones, and 3 purple ones. The total marble in the bag should be: 4+3+4+3= 14. The question is how much the probability to get <span>1 red, 2 green, 1 white and 1 purple.
Ways to take 5 marble out of 14=14C5= 14!/5!9!= </span>2002<span>
</span>Ways to take 1 red marble out of 4= 4C1= 4<span>
</span>Ways to take 2 green marble out of 3= 3C2= 3
Ways to take 1 white marble out of 4= 4C1= 4
Ways to take 1 purple marble out of 3= 3C1= 3
Then the probability would be: 4*3*4*3/ 2002= 144/2002= 72/1001
