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.
Write down a common denominator for 7/8 and 9/10. Then compare the fractions when they have the common denominator.
X=ind tickets
y=coup. tickets x = 38 + y ← # of ticket equation
3x + 5y =730 ← $ of equation
3(38+y) + 5y = 730
114 + 3y + 5y = 730
114 + 8y =730
-114 = -114 → 8y =616 = y= 77 → x= 38 +y → x=38 + 77 → x =115

Answer:
(6, -4)
Step-by-step explanation:
If ABCD is dilated by a factor of 2, you multiply the coordinates by 2. For the coordinate D', you would multiply 3 by 2 to get 6 and you would multiply -2 by 2 to get -4. Answer: (6, -4)
