Hey there!

<h2>ANSWER: x=3</h2><h2>EXPLANATION:</h2>

16+x=19

There is an easy way to solve this question. First, subtract 19 - 16.

19-16=3

Now let's try putting 3 in x to see if it makes sense.

16+x=19\\16+3=19(ANSWER)

It equaled 19. So this is your answer.

Hope this helps!

Answer:

x = 3

Step-by-step explanation:

We can write the equation as 16 + x = 19

To solve we can work backwards, I know the opposite of adding is subracting... so 19 - 16 = 3 which means x is equal to 3.

Hope that helps and have a great day!

Jacob copies 30% of a document. He copies 8 pages. Write the number of pages in the<br>document.​
lana66690 [7]

Answer:

27

Step-by-step explanation:

<h2><u>Number of documents</u></h2>

jacob copies 30% of a document which is 8 pages

we can solve this using cross multiplication

30 %       :        8

100%      :         x

30%x = 100%*8

30% x = 8

x = 8/ 30%

x = 26.667

to 2sf

Evaluate A + 3B if possible. HELP ASAP!
madreJ [45]

Answer:

Not possible.

Step-by-step explanation:

Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.

Order of a matrix with m rows and n columns is m\times n.

Here, matrix A is \left[\begin{array}{ccc}2&-4\\-4&10\\0&-8\end{array}\right]

Matrix B is \left[\begin{array}{ccc}0&-4&6\\2&-10&4\end{array}\right].

Multiplying a matrix by a constant doesn't change its order.

So, order of matrix A is 3\times 2 as it has 3 rows and 2 columns.

The order of matrix 3B is 2\times 3 as it has 2 rows and 3 columns.

Therefore, addition is not possible as the order is different.
