°F=1.8°C−32; 60.6°C
°F=1.8°C−32; 60.6°C

°F=1.8°C+32; 25°C
°F=1.8°C+32; 25°C

°F−32=°C1.8; 81°C
°F−32=°C1.8; 81°C

°F=1.8+°C+32; 43.2°C

Answer 1

To convert from degrees Fahrenheit (°F) to degrees Celsius (°C), the correct equation is:

\[ °C = \frac{°F - 32}{1.8} \]

We can rewrite this as:

\[ °F = 1.8°C + 32 \]

However, based on the options provided, the corresponding conversion equation is (rearranged):

\[ °F - 32 = 1.8°C \]

Now, to find 77°F in °C:

Using the formula:
\[ °C = \frac{77°F - 32}{1.8} \]

Calculating it:
1. Subtract 32 from 77:
\[ 77 - 32 = 45 \]
2. Divide by 1.8:
\[ \frac{45}{1.8} = 25°C \]

So, 77°F is equal to 25°C.

Thus, the correct response from the options is:

**°F=1.8°C+32; 25°C**.
