First fold of a piece of paper produces two smaller pieces of paper
Second fold of the resulting pieces of paper produces 4 smaller pieces of paper.
Third fold of the resulting pieces of paper produces 8 smaller pieces of paper.
Thus, the five letter size pieces of paper folded three times produces 8 x 5 = 40 notes.
Thus, one notepad consists of 40 notes.
If someone wrote ten notes per day, then one notepad will last for 4 days.

Answer:
-80
Step-by-step explanation:
We have: -6 =
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 =
+ 4 - 4 ⇒ -10 = 
Then, multiply by 8 on both sides:
-10 * 8 =
* 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
