The expression provided in the image is:

$\frac{7a + b}{c}$ where:

• $a = 2$
• $b = 7$
• $c = 6$

Now, let's substitute the values of $a$, $b$, and $c$ into the expression:

$\frac{7(2) + 7}{6}$

First, calculate the numerator:

$7(2) + 7 = 14 + 7 = 21$

Now, divide the result by $c = 6$:

$\frac{21}{6} = 3.5$

So, the evaluated result is:

$3.5$

Would you like more details, or do you have any questions?

Here are 5 related questions for practice:

1. What is the value of the expression if $a = 3$, $b = 5$, and $c = 4$?
2. How does changing $b$ affect the value of the expression?
3. Can you simplify the expression $\frac{7a + b}{c}$ for general values of $a$, $b$, and $c$?
4. What happens to the result if $c = 0$ in the expression?
5. How would you evaluate a similar expression, $\frac{5a - b}{c}$, with given values?

Tip: When working with expressions, always simplify step by step and check for division by zero to avoid undefined values.
