A car was sold at $34000. That price was 85℅ of the orginal price. What was the original price?
Art [367]
Hey there! The answer is $40000

<span>A car was sold at $34000. That price was 85℅ of the orginal price.
When we know 85% of the original price we can find 1% of this price by dividing by 85.

1% of the original price = $34000 / 85 = $400
</span>When we know 1% of the original price we can find 100% of this price by multiplying by 100.

100% of the original price = original price = $400 * 100 = $40000
The answer is $40000

~ Hope this helps you!

DUE VERY SOON URGENT PLEASE HELP!!

The values of x are

1. x = 32°,

2. x = 15°,

3. x = 49°,

4. x = 65°,

Explanation:

  • The angle made by any right angle is 90° and the angle made by a straight line is 180°. These are the main equations required to solve the values of x. The first 2 are right angles and the last 2 are straight lines. So the sum of the components within that right angle is 90° and for a straight line is 180°.
  • For diagram 1; 2x° + x° - 6° = 90°, 3x° = 90° + 6° = 96°, x =  \frac{96}{3} = 32°.
  • For diagram 2; 4x° + 3° + x° + 12° = 90°, 5x° = 90° - 15° = 75°, x =  \frac{75}{5} = 15°.
  • For diagram 3; x° + 33° + 2x° = 180°, 3x° = 180° - 33 = 147°, x =  \frac{147}{3} = 49°.
  • For diagram 4; 2x° + 1° + x° - 16° = 180°, 3x° = 180° + 15° = 195°, x = \frac{195}{3} = 65°.

8x+4(4x-3)=4(6x+4)-4​
vaieri [72.5K]

Answer:

x = 24

Step-by-step explanation:

8x + 4(4x - 3) = 4(6x + 4) - 4

8x + 16x - 12 = 24x + 16 - 4

24x - 12 = 24x + 12

24x = 24x + 12 + 12

24x = 24x + 24

24x/24x = 24

x = 24
