Answer:
y = 3
Step-by-step explanation:
2x+6y=5x+4y if x=2
2(2)+6y=5(2)+4y
4+6y=10+4y
-4 =-4
6y=6+4y
-4y= -4y
2y=6
/2=/2
y=3
12 more games.
The current winning percentage is 60%, which is found by dividing 12 by 20 and multiplying by 100 (12 / 20 = 0.60, 0.60 x 100 = 60).
To get a winning streak of 75%, Anne has to win 12 more games in a row. That will mean she will have won 24 out of a total of 32 matches, and this decimal is equal to 0.75. Multiply by 100 to get the percentage of 75%.
