Answer:
b x =-2/3
Step-by-step explanation:
-3(2x+1) + 3x = 6x + 3
Distribute
-6x -3 +3x =6x+3
Combine like terms
-3x-3 = 6x+3
Add 3x to each side
-3x+3x-3 = 6x+3x+3
-3 = 9x+3
Subtract 3 from each side
-3-3 = 9x+3-3
-6 = 9x
Divide by 9
-6/9 = 9x/9
-2/3 =x
Answer: 1

85/7=12 with a remainder of 1
Expected number of wins=number of plays times the probability of winning
w=20(14.5/100)
w=20(0.145)
w=2.9
w≈3
So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)
