Answer:
340
Step-by-step explanation:
10 ×16=160
12×15=180
160+180=340 so a total of 340 calendars
First question: 12 people each play 11 times, so 12 * 11 = 132, there will be 132 matches if each player plays one match against each of the other athletes.
Multiply the equation x+y =4 by -5
The resultant would be-
-5x -5y = -20
Adding this with 5x +2y =8
Then, the resulting would be,
-3y = -12
∴ y=4
and x=4-4 =0
