To solve the equation "five times a number plus two is 17," we can set it up as follows:
Let the unknown number be \( x \). The equation can be written as:
\[ 5x + 2 = 17 \]
To solve for \( x \), follow these steps:
1. Subtract 2 from both sides of the equation:
\[ 5x = 17 - 2 \]
\[ 5x = 15 \]
2. Now, divide both sides by 5 to isolate \( x \):
\[ x = \frac{15}{5} \]
\[ x = 3 \]
Therefore, the number is **3**.
So the answer is **C) 3**.
