lisabon 2012 [21]

Answer:

After 16 rounds the champion of Ping-Pong player can be determined.

Step-by-step explanation:

This is an example of geometric progression,

First term = 65,536

$\texttt{Common ratio = }\frac{1}{2}$

Now we need to find which term is 1 in this GP.

N th term of GP is given by

$t_n=ar^{n-1}$

Substituting

$1=65536\times \left ( \frac{1}{2}\right )^{n-1}\\\\\frac{1}{65536}=\left ( \frac{1}{2}\right )^{n-1}\\\\2^{n-1}=65536\\\\2^{n-1}=2^{16}\\\\n=17$

Seventeenth term of this GP is 1.

That is after 16 rounds the champion of Ping-Pong player can be determined.

Please solve (X+2) 3 = (x-4) 5

lora16 [44]

Answer:

x= 13

Step-by-step explanation:

(X+2) 3 = (x-4) 5

distribute on both sides: 3x + 6 = 5x - 20

add 20 to both sides: 3x + 26 = 5x

subtract 3x from both sides: 26 = 2x

divide both sides by two: 13 = x
