Chip takes 2 pages of notes every day, 5 days a week, for each of his 5 classes. This means he takes 2 * 5 * 5 = 50 pages of notes per week.
After 6 weeks, he will take a total of 50 * 6 = 300 pages of notes.
His notebook paper comes in packs of x sheets of paper per pack, so the total number of packs he will use is 300 / x.
We are given that the total number of packs he will use is 3, so we can write: 300 / x = 3.
Multiplying both sides by x, we get: 300 = 3x.
Dividing both sides by 3, we get: x = 100.
The value of x is 100.
#### 100
The answer is: 100
