If the weight of a package is multiplied by 5/7 the result is 40.5 pounds. Find the weight of the package.

1 answer:

Well, it would become 5/7x=40.5. Divide both sides by 5/7, so it is 40.5 * by the reciprocal of 5/7 (7/5). The answer is 56.7 pounds.

Please help!! Solve the system using an augmented matrix. Show all work

marishachu [46]

Answer:

The solution of the system is: $x=2, y=5$

Step-by-step explanation:

The given system of equations is.......

$-x-3y=-17\\ \\ 2x-6y=-26$

So, the augmented matrix will be: $\left[\begin{array}{cccc}-1&-3&|&-17\\2&-6&|&-26\\\end{array}\right]$

Now, we will transform the augmented matrix to the reduced row echelon form using row operations.

Row operation 1 : Multiply the 1st row by -1. So..........

$\left[\begin{array}{cccc}1&3&|&17\\2&-6&|&-26\\\end{array}\right]$

Row operation 2: Add -2 times the 1st row to the 2nd row. So.......

$\left[\begin{array}{cccc}1&3&|&17\\0&-12&|&-60\\\end{array}\right]$

Row operation 3: Multiply the 2nd row by $-\frac{1}{12}$ . So.......

$\left[\begin{array}{cccc}1&3&|&17\\0&1&|&5\\\end{array}\right]$

Row operation 4: Add -3 times the 2nd row to the 1st row. So........

$\left[\begin{array}{cccc}1&0&|&2\\0&1&|&5\\\end{array}\right]$

Now, from this reduced row echelon form of the augmented matrix, we can get that $x=2$ and $y=5$

So, the solution of the system is: $x=2, y=5$

The overall change in the stock price would be the increase minus the decrease.

The increase is 1/2

The decease is 5/6

1/2 - 5/6 =

Change 1/2 to 3/6

3/6 - 5/6 =

simplify
