Answer :
Answer:
The answer is 7 °C.
Step-by-step explanation:
Using the formula given, we can see that we are inputting a Fahrenheit value to solve for a Celsius value. Therefore, we just need to plug it in to the formula.
[tex]45 = \frac{9}{5}C +32[/tex].
Now, we can subtract 32 from both sides to isolate [tex]\frac{9}{5} C[/tex] from the rest of the equation. This gives us [tex]13 = \frac{9}{5} C[/tex].
Now, we just multiply by the reciprocal of the fraction in front of C to make it vanish and also apply that process to 13. Therefore, we do this:
[tex]\frac{5}{9} * 13 = 7.22222[/tex]
Therefore, C ≈ 7° because of rounding requirements.
Answer:
About 7 degrees
Step-by-step explanation:
[tex]45=9/5C+32 \\\\13=9/5C \\\\C\approx 7[/tex]
Hope this helps!
