Write the system in a matrix equation. Then, find the determinant of the matrix containing the coefficients.
Shtirlitz [24]

Answer:

See below for the matrix

D = 100

Step-by-step explanation:

\left[\begin{array}{cccc}3&2&1&-8\\-1&-2&4&7\\1&-6&-3&15\end{array}\right]

         3    2    1

D =   -1    -2    4    =   3(-2)(-3) + 2(4)(1) + 1(-1)(-6)  

         1    -6   -3

                                    - 1(-2)(1) - 3(4)(-6) - 2(-1)(-3)

                           =  18 + 8 + 6 + 2 + 72 - 6

                           =  100

Sorry, I can't type the vertical bars.

The length of a rectangle is 6 ft longer than its width.
nasty-shy [4]

Answer:

135ft²

Step-by-step explanation:

Width = w

Length = w + 6

Perimeter = 48

Perimeter = 2(l + w)

Perimeter = 2(w + 6 + w) = 48

2(2w + 6) = 48

4w + 12 = 48

4w = 48 - 12

4w = 36

w = 36/4

width = 9

length = w + 6 = 9 + 6 = 15

Area = length × width

= 15 × 9

= 135 ft²

You own a small comic book store. 2/3 of your store's floor space is dedicated to
svetoff [14.1K]

Answer:

66.66

Step-by-step explanation:

So for this one all you really have to do is turn 2/3 into a precent which is pretty easy.

This fist step to this would just be dividing 2 and 3

2/3=0.66666666666666666666 (and on and on and on)

Now just move the decimal 2 times to the right

66.6666666666666666666666

And of course round it, and in this case to the hundreth place

66.66
