Correct scientific notation has only one number to the left of the decimal point.

The correct one would be: 3.4 x 10(exponent 3)

For this question, you have to take Least Common Multiplier for which in this case will be "45" as, the denominators can get similar and get multiplied by a same value to form a similar expression. This allows us to cancel out them by common factors. Full process shown below.

$\mathbf{Given \: \: Expression: \: \dfrac{x - 4}{5} = 9 - \dfrac{2x - 41}{9}}$

$\mathbf{\dfrac{x - 4}{5} \times 45 = 9 \times 45 - \dfrac{2x - 41}{9} \times 45}$

$\mathbf{9(x - 4) = 405 - 5 (2x - 41)}$

$\mathbf{9x - 36 = 405 - 10x + 205}$

$\mathbf{9x - 36 = - 10x + 610}$

$\mathbf{9x - 36 + 36 = - 10x + 610 + 36}$

$\mathbf{9x = - 10x + 646}$

$\mathbf{9x + 10x = - 10x + 646 + 10x}$

$\mathbf{19x = 646}$

$\mathbf{\dfrac{19x}{19} = \dfrac{646}{19}}$

$\mathbf{\therefore \quad x = 34}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is; \: \: x = 34}}}$

Hope it helps.

How to solve this step by step n get the answer

lana66690 [7]

Answer:

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$

Step-by-step explanation:

The Slope Intercept Form of the line is given to us . The equations given are ,

$\implies y + 3x = 7$

$\implies y + \dfrac{1}{2}x = -4$

Now we know the standard equation of slope intercept form , is

$\implies y = mx + x$

Where ,

m is slope
c is y intercept .

So , we can write about the equations as ,

$\implies y = -3x + 7$

$\implies y = - \dfrac{1}{2}x -4$

On comparing to the Standard form ,

<u>Answer </u><u>1</u><u> </u><u>:</u><u>-</u><u> </u>

$\implies m_1 = -3$

$\implies y - intercept = 7$

<u>Answer </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$
