A car salesman makes 2% commission on all cars, x, that he sells. How much commission does he make?
HACTEHA [7]

Answer: 0.02x

Step-by-step explanation:

The value of the cars the salesman makes is x in this instance.

The salesman makes a 2% commission on every sale so this can be represented by multiplying 2% by the value of the cars which in this case is x.

= 2% * x

= 0.02 * x

= 0.02x

If for instance he sells $40,000 worth of cars, his commission would be:

= 0.02 * x

= 0.02 * 40,000

= $800

NEED HELP ASAP<br>algebra 2​
Luden [163]

Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)

3(x + 1) = -2(x - 1) - 4
Svetllana [295]

Answer:

<h2><em><u>x = -1</u></em></h2>

Step-by-step explanation:

<em><u>1. Distribute</u></em>

3x + 3 = -2x + 2 - 4

<em><u>2. Simplify</u></em>

-2x + 2 - 4

2-4 = -2

-2x - 2

<em><u>3. Solve</u></em>

3x + 3 = -2x - 2

+2x       +2x

<em><u>4. Cont. Solving</u></em>

5x + 3 = -2

     -3     -3

5x = -5

<em><u>5. Divide by 5</u></em>

5x = -5

/5      /5

<h2><em><u>x = -1</u></em></h2><h2><em><u /></em></h2>

Hope this helped,
