Answer:
5 more games to be won for the 50% success rate.
Step-by-step explanation:
Total number games played = 500
Number of successful games = 49% of 500
= 500 × 
= 245
Number of successful games for the success of 50% = 500 × 
= 250
Therefore, number of game you have to win more = 250 - 245
= 5 games
-3x from both sides so it looks like 2x=20 and divide by 2 and x=10
1. 12in (1ft)+X=28in
2. 6in.+X=42
3. 170.5sq.ft./15.5=x
4. 120ft/12ft=x10sec.
