Answer:

x=30

Step-by-step explanation:

(30+x)+30+9x=360

We move all terms to the left:

(30+x)+30+9x-(360)=0

We add all the numbers together, and all the variables

(x+30)+9x+30-360=0

We add all the numbers together, and all the variables

9x+(x+30)-330=0

We get rid of parentheses

9x+x+30-330=0

We add all the numbers together, and all the variables

10x-300=0

We move all terms containing x to the left, all other terms to the right

10x=300

x=300/10

x=30

What is the product?

kobusy [5.1K]

Answer:

$\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$

Step-by-step explanation:

We have the product, $\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0& 6& 2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$ .

As, we have the product of a 3×3 and 3×1 matrix, the resultant matrix will be of order 3×1.

So, we get,

$\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0&6&2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$

⇒ $\begin{bmatrix}3\times 2+6\times 0+1\times 1\\ 2\times 2+4\times 0+0\times 1\\ 0\times 2+6\times 0+2\times 1\end{bmatrix}$

⇒ $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .

Thus, the resulting product is $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .

Please i need help whats 1/5x - 2 = 4

Orlov [11]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{1}{5} x - 2= 4 \\$

Add sides 2

$\frac{1}{5} x - 2 + 2 = 4 + 2 \\$

$\frac{1}{5} x = 6 \\$

Multiply sides by 5

$5 \times \frac{1}{5} x = 5 \times 6 \\$

$x = 30$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{1}{5x} - 2 = 4 \\$

Add sides 2

$\frac{1}{5x} - 2 + 2 = 4 + 2 \\$

$\frac{1}{5x} = 6 \\$

Inverse both sides

$5x = \frac{1}{6} \\$

Divide sides by 5

$\frac{5x}{5} = \frac{1}{6} \div 5 \\$

$x = \frac{1}{6} \times \frac{1}{5} \\$

$x = \frac{1}{30} \\$
