Water boils at [tex]100^{\circ}[/tex] Celsius or [tex]212^{\circ}[/tex] Fahrenheit. Water freezes at [tex]0^{\circ}[/tex] Celsius or [tex]32^{\circ}[/tex] Fahrenheit.

If the weather forecaster says it will be [tex]25^{\circ}[/tex] Celsius today, write and solve a linear equation to find what Fahrenheit temperature this is.

Answer :

To convert a Celsius temperature to Fahrenheit, you can use the following linear equation:

[tex]\[ \text{Fahrenheit} = \left(\text{Celsius} \times \frac{9}{5}\right) + 32 \][/tex]

Here's how you can apply this formula to find out what 25°C is in Fahrenheit:

1. Identify the given Celsius temperature:
You are given that today’s temperature is [tex]\(25^\circ\)[/tex] Celsius.

2. Substitute the Celsius temperature into the formula:
Replace "Celsius" in the formula with 25.

3. Perform the multiplication:
[tex]\[ 25 \times \frac{9}{5} = 45 \][/tex]

4. Add 32 to the result:
[tex]\[ 45 + 32 = 77 \][/tex]

Therefore, the temperature of 25°C is equivalent to [tex]\(77^\circ\)[/tex] Fahrenheit.
