Answer: A. 20 is the answer.

Step-by-step explanation:

x+40 = 3x

0=-20.5x+16.35x-0.1245
Pachacha [2.7K]

The value of x in the given equation -20.5x+16.35x -0.1245 = 0\\ is 0.03

<u>Step-by-step explanation:</u>

The given equation is that -20.5x+16.35x -0.1245 = 0\\

<u>The steps to be followed to solve the equation are :</u>

Add the like terms together to reduce the equation in a simplified form.

Here, there are two x terms and they must be reduced to a single term.

For this, add the both terms together so that the equation is simplified into one x term and a constant term.

⇒ (-20.5x+16.35x) - 0.1245 = 0

⇒ 4.15x-0.1245 = 0

To eliminate the constant term on the left side of the equation, add 0.1245 on both sides.

⇒ 4.15x -0.1245+0.1245 = 0.1245

⇒ 4.15x = 0.1245

Now, the equation is further simplified by dividing 4.15 on both sides,

⇒ 4.15x / 4.15 = 0.1245/4.15

⇒ x = 0.03

Therefore, the value of x is 0.03

If i'm getting 20% commission from a monthly sale of $800000 what is my 30% in month of sale be?
Oksana_A [137]

Answer:

Your commission check for the 20% would be $160,000 and your 30% would be $240,000.

Step-by-step explanation:

To find each of these, multiply the total number of sales by the percentage of the commission.

$800,00*20% = $160,000

$800,000*30% = $240,000

Find the value of cos x° + sin yº ​
MA_775_DIABLO [31]

Answer:

1.84

Step-by-step explanation:

The given arc is a part of a unit circle centered at origin.

The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.

So, for angle equal to x°, the x coordinate represents cos (x)°.

So, cos x° = 0.86

Similarly, the y-coordinate of angle y represent \sin y°.

So, \sin y° = 0.98

Therefore, the value of cos (x)° + \sin y° = 0.86 + 0.98 = 1.84.
