First we have to find how much Kyle earned taking to consideration only 38h at work
So 38*14$=532$ 
Now, to find commission bonus we have to 1200-532=668
Finally, we can find what dollar amount of car Kyle must sell.
We know that 668 is 8% of that number. We can use proportion and cross multiplying, so:
8% ----------- 668
100% --------x
x= \frac{100*668}{8}=8350$ - its the result.

Answer:

  13

Step-by-step explanation:

Perhaps the most straightforward way to find the value of the given function is to first solve the equations for x and y. The results can be substituted into your expression to find the value you want.

__

<h3>solving the system</h3>

We notice the y-coefficients are opposites, so we can eliminate the y-variable by adding the equations.

  (2x -y) +(x +y) = (3) +(1)

  3x = 4 . . . . . . simplify

  x = 4/3 . . . . . divide by 3

The value of y can be found from the second equation:

  4/3 +y = 1 . . . . substitute for x

  y = -1/3 . . . . . . subtract 4/3

<h3>expression value</h3>

The value of 8x-7y is found by substituting the x- and y-values into this expression:

  8(4/3) -7(-1/3) = 32/3 +7/3 = 39/3 = 13

The value of 8x-7y is 13.

_____

<em>Additional comment</em>

You can also work out what combination of the two equations will give 8x -7y. That turns out to be 5 times the first minus 2 times the second:

  5(2x -y) -2(x +y) = 5(3) -2(1)

  10x -5y -2x -2y = 15 -2

  8x -7y = 13

__

The coefficients 5 and -2 are found by solving the system of equations ...

  a(2x -y) +b(x +y) ≡ 8x -7y   ⇒   {2a +b = 8, -a +b = -7}

Line a is parallel to line b, m∠1=2x +44, and m∠5x+38. Find the value of x.
Soloha48 [4]

2x + 44 = 5x + 38
5x - 2x = 3x
44 = 3x + 38
44 - 38 = 6
6 = 3x
2 = x

Mei does 6 problems in 18 minutes. How many can she complete in 12 minutes
Dmitriy789 [7]
Do cross multiplication

  <u>6</u>  =  <u>x</u>
 18    12

Now cross multiply

(6)(12) = (18)(x)

       72 = 18x

Divide both sides by 18
     
    
     <u>72</u>  = <u>18x</u>
     18      18

      4   = x

So tMei can complete 4 problems in 12 minutes.

Witch method will NOT get you to the point (1.5, 4)?
Bad White [126]
Left down, or “Starting at the origin, go 4 spaces to the right and then 1and1/2 spaces up.” This would bring you to the point (4,1and1/2)
