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 $\frac{1}{2}$ .

A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 40% off clearan

Hatshy [7]

Answer: He would pay 45% of the original price.

Step-by-step explanation:

Since we have given that

Let the original price of item be 'x'

Rate mark down by 25%

Amount of marked down would be

$\dfrac{25}{100}\times x\\\\=0.25x$

Amount after marked down becomes

$x-0.25x\\\\=0.75x$

Additional clearance items by 40% off

Amount of additional off is given by

$\dfrac{40}{100}\times 0.75x\\\\=0.4\times 0.75x\\\\=0.3x$

After additional off, the amount becomes,

$0.75x-0.3x\\\\=0.45x$

Hence, he would pay 45% of the original price.
