Alex
The matrix equation that represents this situation is

\left[\begin{array}{ccc}3&2&0\\1&0&4\\3&1&1\end{array}\right]*\left[\begin{array}{ccc}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}13.50\\16.50\\14.00\end{array}\right]

Use technology to find the inverse of matrix A:

A^{-1}=  \left[\begin{array}{ccc}-\frac{2}{5}&-\frac{1}{5}&\frac{4}{5}\\
\frac{11}{10}&\frac{3}{10}&-\frac{6}{5}\\\frac{1}{10}&\frac{3}{10}&-\frac{1}{5}\end{array}\right]

Multiplying A inverse by B, we get the solution matrix

What is the value of x in the equation –x = 2 – 3x + 6?
Aneli [31]

Answer:

x=4

Step-by-step explanation:

Let's solve your equation step-by-step.

−x=2−3x+6

Step 1: Simplify both sides of the equation.

−x=2−3x+6

−x=2+−3x+6

−x=(−3x)+(2+6)(Combine Like Terms)

−x=−3x+8

−x=−3x+8

Step 2: Add 3x to both sides.

−x+3x=−3x+8+3x

2x=8

Step 3: Divide both sides by 2.

2x/2 = 8/2

x=4

Select the correct answer.
Leno4ka [110]

Answer:

  A.  200 packages

Step-by-step explanation:

The number of packages per roll can be found by dividing the length of a roll by the length of tape needed for each package.

__

For each package:

  (2.375 in/piece)×(4 piece/package) = 9.5 in/package

Per roll:

  (1900 in/roll) / (9.5 in/package) = (1900/9.5) packages/roll

  = 200 packages/roll

The machine can seal 200 packages with a roll of tape 1900 inches long.
