The formula for conversion between Fahrenheit and Celsius is
`""^@F=X+(1.8xx^@C)`
What is factor X ?

Options

A. 32
B. 22
C. 98
D. 42

Explanation

To find the factor \( X \) in the formula for conversion between Fahrenheit and Celsius, we start with the known relationship between the two temperature scales. The formula is given as:

\[ F = X + 1.8 \times C \]

where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius.

### Step-by-Step Solution:

1. **Understand the relationship between Celsius and Fahrenheit**:
The standard formula for converting Celsius to Fahrenheit is:
\[ F = \frac{9}{5}C + 32 \]

2. **Rewrite the standard formula**:
We can express this in a form that matches the given formula:
\[ F = 1.8C + 32 \]
Here, \( 1.8 \) is the conversion factor from Celsius to Fahrenheit.

3. **Identify the components in the given formula**:
The given formula is:
\[ F = X + 1.8C \]
By comparing this with the rewritten standard formula \( F = 1.8C + 32 \), we can see that both expressions are equal.

4. **Set the equations equal to each other**:
From the comparison, we can equate the constant terms:
\[ X = 32 \]

5. **Conclusion**:
Therefore, the factor \( X \) is:
\[ \boxed{32} \]
