Answer:
x = 10
Step-by-step explanation:
Two less than three times a number is 28
Let's break it up.
2 less than: -2
3 times a number: 3x (x is representing a number")
is 28: = 28
So, let's put that together.
Two less than three times a number is 28
3x - 2 = 28
Now, let's solve this.
First, let's isolate the x.
To do this, we must add 2 to each side.
3x - 2 = 28
+2 +2
3x - 2 + 2 = 3x
28 + 2 = 30
We have 3x = 30
Now, we must simplify.
To do this, we must divide each side by 3.
This, in term, will tell us what x equals.
3x = 30
--- ----
3 3
3x/3 = x
30/3 = 10
x = 10

<h3>Is the product of two matrices commutative?</h3>
In linear algebra, we define the product of two matrices as follows:
, where 
, 
and 
(1)
Where each element of the matrix is equal to the following dot product:
![c_{ij} = \left[\begin{array}{cccc}a_{i1}&a_{i2}&\ldots&a_{ip}\end{array}\right]\,\bullet\,\left[\begin{array}{ccc}b_{1j}\\b_{2j}\\\vdots\\b_{pj}\end{array}\right]](https://tex.z-dn.net/?f=c_%7Bij%7D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7Da_%7Bi1%7D%26a_%7Bi2%7D%26%5Cldots%26a_%7Bip%7D%5Cend%7Barray%7D%5Cright%5D%5C%2C%5Cbullet%5C%2C%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Db_%7B1j%7D%5C%5Cb_%7B2j%7D%5C%5C%5Cvdots%5C%5Cb_%7Bpj%7D%5Cend%7Barray%7D%5Cright%5D)
, where 1 ≤ i ≤ m and 1 ≤ j ≤ n. (2)
Because of (2), we can infer that the product of two matrices, no matter what dimensions each matrix may have, is not <em>commutative</em> because of the nature and characteristics of the definition itself, which implies operating on a row of the <em>former</em> matrix and a column of the <em>latter</em> matrix.
Such <em>"arbitrariness"</em> means that <em>resulting</em> value for 
will be different if the order between and 
is changed and even the dimensions of 
may be different. Therefore, the proposition is false.
