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

°F−32=°C1.8; 81°C
°F−32=°C1.8; 81°C

°F=1.8+°C+32; 43.2°C
°F=1.8+°C+32; 43.2°C

°F=1.8°C+32; 25°C

Answer 1

To convert degrees Fahrenheit (°F) to degrees Celsius (°C), we can use the following equation:

\[ °C = \frac{°F - 32}{1.8} \]

Now, let's convert 77°F to °C using the formula:

\[ °C = \frac{77 - 32}{1.8} \]

Calculating this step by step:

1. Subtract 32 from 77:

\[ 77 - 32 = 45 \]

2. Divide by 1.8:

\[ °C = \frac{45}{1.8} \approx 25 \]

Therefore, 77°F is approximately 25°C.

Among the options provided, the correct equation is:

\[ °F = 1.8°C + 32; \quad 25°C \]

To summarize:
- The correct equation is: \( °F = 1.8°C + 32 \)
- The value of 77°F in °C is approximately 25°C.
