Answer: 93
Explanation:
Firstly, we need to know the rural.scire for the 4 tests. Since the mean for the 4 tests is a 92, the total score will be:
= 4 × 92
= 368
Since we want to know the score for he 4th test, we add the score for the 3 tests that she remembers and subtract from 368. This will be:
= 368 - (100 + 95 + 80)
= 368 - 275
= 93
She had 93 in her last test.

Answer:
22 games
132 games
58 - 40
Explanation:
Given that:
Total Number of teams = 12
Number of times a team play every other = 2 (home and away)
Number of ties = 34
Let :
home wins = x
Away wins = x - 18
1: How many games did any one particular team play?
(Total Number of teams - 1) * number of times a team play every other
(12 - 1) * 2
11 * 2 = 22 games
2: How many total games were played in the league?
(Number of games played per team * number of teams) / 2
(22 * 12) / 2
= 264 /2
= 132 games
3: What was the Won-Loss record by Home Teams last season?
Total number of games = 132
Home wins + away wins + ties = 132
x + x - 18 + 34 = 132
2x + 16 = 132
2x = 132 - 16
2x = 116
x = 58
Home team wins = 58
Away team wins = home team loss = 58 - 18 = 40
Hence, Won - Loss record by Home team :
58 : 40
