How do you solve this problem: x/3-8=2. What do you get for x step by step please.

1 answer:

3 0

Step 1: x/3-8=2
Step 2: x/-5=2
Step 3: -10/-5=2
Step 4: x=-10

Step 1: First, subtract 8 from 3. 3-8=-5.
Step 2: Replace 3-8 with -5.
Step 3: To find x, multiply -5 and 2. The answer is -10.

K = [ 14 -13 0 3 8 -1 -10 -2 5 ] find the determinant of K

spin [16.1K]

I suppose <em>K</em> is the matrix

$K = \begin{bmatrix}14 & -13 & 0 \\ 3 & 8 & -1 \\ -10 & -2 & 5\end{bmatrix}$

To compute det(<em>K</em>), you can use a simple cofactor expansion along the first row:

$\det(K) = 14\times\det\begin{bmatrix}8 & -1 \\-2 & 5\end{bmatrix} - (-13)\times\det\begin{bmatrix}3 & -1 \\ -10 & 5\end{bmatrix} + 0\times\det\begin{bmatrix}3 & 8 \\ -10 & -2\end{bmatrix} \\\\ \det(K) = 14\times(8\times5-(-1)\times(-2)) + 13\times(3\times5-(-1)\times(-10)) + 0 \\\\ \det(K) = 14\times38 + 13\times5 = \boxed{597}$

Step-by-step explanation:

markup is 3.50(0.60) = $2.10

sales price is 3.50 + 2.10 = $5.60

one could also just multiply the wholesale price by 1.60

3.50(1.60) = $ 5.60
