Answer:
1. x = 24
2. r = -7
3. x = - 110
4. x = 10/3
Step-by-step explanation:
1. x/6 = 4 => x = 6 · 4 = 24
2. r/7 = -1 => r = -1 · 7 = -7
3. -x/11 = 10 => -x = 11 · 10 = 110 => -x = 110 / ·(-1)
Now we will multiply the both sides with (-1) and get
x = -110
4. x/4 = 5/6 It's the same as proportion x : 4 = 5 : 6
Now we will multiply external and internal members and get
6 x = 4 · 5 => 6 x = 20 => x = 20/6
Now we reduce the numerator and the fractional denominator with the number two and get
x = 10/3

Answer: He could have played more than 3 games.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality.
I golf club charges $10 to join and $5 per game: So, the cost of playing golf is equal to $10 (joining price) plus the product of the number of games played (x) and the price per game (5).
That expression must be higher than 25, since john paid more than $25.
Mathematically speaking
10+ 5 x > 25
Solving for x
5x >25-10
5x >15
x >15/5
x> 3
He could have played more than 3 games, since his cost was higher ( not equal or higher) than 25.
