Evaluate the following arithmetic expressions:
`85-55+18xx5-:9`

Answer

To evaluate the arithmetic expression \( 85 - 55 + 18 \times 5 \div 9 \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

### Step-by-Step Solution:

1. **Identify the expression**:
\[ 85 - 55 + 18 \times 5 \div 9 \]

2. **Apply the order of operations (BODMAS/PEMDAS)**:
- First, we perform the division and multiplication from left to right.

3. **Calculate the division**:
\[ 18 \times 5 \div 9 \]
- First, divide \( 5 \) by \( 9 \):
\[ 5 \div 9 = \frac{5}{9} \text{ (but we can also calculate it as follows: } 18 \div 9 = 2 \text{, so we can multiply it by 5)} \]
- Thus, \( 18 \div 9 = 2 \).

4. **Now multiply**:
\[ 2 \times 5 = 10 \]

5. **Substitute back into the expression**:
\[ 85 - 55 + 10 \]

6. **Perform the subtraction**:
\[ 85 - 55 = 30 \]

7. **Now add**:
\[ 30 + 10 = 40 \]

### Final Answer:
\[ \text{The evaluated result is } 40. \]
