Answer:

Colin has 8 sheets remaining for his third class.

Step-by-step explanation:

Let's summarize the details:

Total number of sheets of paper = $x$

The number of sheets used in the first class is five less than half of the total number.

We create the equation:

$\text{Number of pieces of papers used for 1st class =} \dfrac{x}{2} -5...... (1)$

Moreover, for the second class, the number of sheets used is two more than the amount used in the first class.

$\text{Number of pieces of papers used for 2nd class =} \dfrac{x}{2} -5+2 = \dfrac{x}2 -3...... (2)$

Therefore, the total sheets remaining for the third class is calculated as: Total sheets - Sheets used in the first class - Sheets used in the second class

$\text{number of pieces of papers left for the third class = }x-(\dfrac{x}{2}-5)-(\dfrac{x}{2}-3)\\\Rightarrow x-\dfrac{x}2-\dfrac{x}2+5+3\\\Rightarrow x-x+5+3\\\Rightarrow 8$

Consequently, the final result is:

Colin has 8 sheets remaining for his third class.
