A) x = 0, 2
Step-by-step explanation:
(x + 4) / 6x = 1 / x
this is a proportion, so you can cross-multiply and get:
x(x + 4) = 6x
x² + 4x = 6x
x² - 2x = 0
x(x - 2) = 0
x = 0
x - 2 = 0 so, x = 2

Answer:
S = 380 - 380*80%
Step-by-step explanation:
Given:
- The original price of the desk: $380
- Discount: 20%
So, the new price of the desk after discounting is:
380(100% - 20%)
= 380*80%
= 304$
The amount of money saved: 380 - 304 = 76$
Hence, the equation can be used to determine the amount of money saved is:
Saving = 380 - 380*80%
Hope it will find you well.
