Step-by-step explanation:
PRIMERO encuentras x
3x + 2y = 56
<u>5x - 2y = 24</u>
8x = 80
x = 80/ 8 = 10
LUEGO PARA ENCONTRAR y TOMAS cualquiera de las dos DE LAS
ECUACIONES Y SUSTITUYES x
3(10) + 2y = 56
30 + 2y = 56
y = 56 - 30/2 = 13
Using a geometric sequence, it is found that after 3 rounds, 8 teams are left.
In a geometric series, the quotient between consecutive terms is always the same, and it is called common ratio q.
The general equation of a geometric series is given by:
In which is the first term.
In this problem:
- 64 teams were invited, thus .
- After each round, half the teams are eliminated, thus .
The <u>number of teams after 3 rounds</u> is the 4th term of sequence, as the first is the initial number(0 rounds), thus:
After 3 rounds, 8 teams are left.
