Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 1/2

How do I solve this equation ???

To solve for the variable $b$ , we have to make it alone. The first thing we do is add $6.5$ to both sides of the equation:

$13.7b-6.5+6.5=-2.3b+8.3+6.5\\13.7b=-2.3b+14.8$

Now add $2.3$ to both sides:

$13.7b+2.3b=-2.3b+14.8+2.3b\\16b=14.8$

Finally, divide both sides by 16 to get the final answer:

$\frac{16b}{16} =\frac{14.8}{16}$

Therefore,

$b=0.3$

Hope this helps!

(PLEASE ANSWER + BRAINLIEST ANSWER!!)

murzikaleks [220]

The arc length, radius and the included angle are related as

$r\theta=\widehat {XYZ}$ where $\theta$ is in radians.

The radius $r$ is given by

$r=\frac{\widehat {XYZ} }{\theta} \\ r=\frac{10.8}{1.8} \\ r=6\;units$

Correct choice is (B).

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.
