Answer:
15
Step-by-step explanation:
Divide 5/8 by 13 2/3 and you should get your answer.
The best way to solve this equation is to multiply the probability of them each getting a cotton sweater. The first fraction would be 1/2 because half of the sweaters are cotton at this point. The second one would be 6/13 because there are now six cotton sweaters out of the thirteen sweaters left. The third would be 5/12 because there are now five cotton sweaters out of the twelve sweaters left. The last one would be 4/11 because there are now four cotton sweaters out of the eleven sweaters left. you would then multiply 2 by 13 getting 26, then multiply 26 by 12 getting 312. Finally, multiply 312 by 11 getting 3,432, which would be your denominator. You would then multiply 6, 5, and 4 getting 120, your numerator. Getting your simplified answer 5/143.
Answer: x=-4.8
Step-by-step explanation:
Given
-10x+4=52
Subtract 4 on both sides
-10x+4-4=52-4
-10x=48
Divide -10 on both sides
-10x/-10=48/-10
x=-4.8
Hope this helps!! :)
Please let me know if you have any questions
4 yellow + 6 green + 10 purple = 20 total tiles
1st draw P purple: 10 purple/20 total
2nd draw P purple: 9 purple/19 total
Probability purple then purple (no returns):
= 90/380
= 45/190
= 9/38
