Answer:

Multiply row 1 by $\frac{1}{2}$ .

Step-by-step explanation:

The augmented matrix of the system of linear equation is described below:

$\left[\begin{array}{cccc}2&1&-1&-8\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]$

Where $a_{11} = 2$ , if we need to create $a_{11} = 1$ , we need to multiply row 1 by $\frac{1}{2}$ , that is to say:

$\left[\begin{array}{cccc}1&\frac{1}{2} &-\frac{1}{2} &-4\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]$

Hence, the correct answer is: Multiply row 1 by $\frac{1}{2}$ .

$12 = \frac{1+a}{1-a} => 12(1-a)= 1+ a \\=> 12 -12a = 1 + a => 12a+1 = 12-1 \\=> 13a = 11 => a= \frac{11}{13}$

ok done. Thank to me :>

Answer: 8365 meters.

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the exercise:

- Mount St. Helen’s is 2549.652 meter above sea level.

- 1 foot=0.3048 meters

2. Let's call x the height in feet, therefore, you have:

$x=\frac{(1ft)(2549.652m)}{0.3048m}\\x=8365m$
