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.
Answer:
Combine like terms
Step-by-step explanation:
The first step in such equations is to simplify the equation which is done most often by combining like terms, and by combining like terms i mean for example:
1 + 5 + 3x = 4y + z
You will combine the like terms (those that can be added or subtracted):
6 + 3x = 4y + z
In our example, combining terms would be adding 2x/3 and 1x/3 to give
3x/3 + 2 = 5
The equation is now simple and easy to solve as you simplify 3x/3 to 1x and then proceed to rearrange the equation to yield the value of x
Hope this helps!

Step-by-step explanation:
Answer:
cos(x) = square root 2 over 2; tan(x) = 1
Step-by-step explanation:

was, before it was rationalized,

Therefore,

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,
and
since tangent is side opposite (1) over side adjacent (1),
tan(x) = 1
