The problem asks to evaluate the given algebraic expressions by substituting the provided values for the variables $a$, $b$, and $c$. The values given are $a=3$, $b=5$, and $c=6$.

1. Problem Description

The problem asks to evaluate the given algebraic expressions by substituting the provided values for the variables $a$, $b$, and $c$. The values given are $a=3$, $b=5$, and $c=6$.

2. Solution Steps

1. $a+5$: Substitute $a=3$ into the expression: $3+5=8$.

2. $15-c$: Substitute $c=6$ into the expression: $15-6=9$.

3. $4b$: Substitute $b=5$ into the expression: $4 \times 5 = 20$.

4. $\frac{18}{c}$: Substitute $c=6$ into the expression: $\frac{18}{6}=3$.

5. $20-a$: Substitute $a=3$ into the expression: $20-3=17$.

6. $11b$: Substitute $b=5$ into the expression: $11 \times 5 = 55$.

7. $\frac{45}{b}$: Substitute $b=5$ into the expression: $\frac{45}{5}=9$.

8. $a-2$: Substitute $a=3$ into the expression: $3-2=1$.

9. $a+b+c$: Substitute $a=3$, $b=5$, and $c=6$ into the expression: $3+5+6=14$.
