Temperature measurements are converted between degrees Fahrenheit (F) and degrees Celsius (C) by the formula F = (9/5)C + 32°.

The temperature in Dallas rose from the morning temperature of 49°F to the afternoon high of 75°F. What was the difference in temperature in degrees Celsius, to the nearest degree?
Im thinking 26 but seems too simple to solve

anonymous · Answer

$$\frac59 (F-32)=C$$

anonymous · Answer

you need to convert from F to C first

campbell_st · Answer

rewrite the equation to make C the subject

$$C = 5/9(F - 32)$$

now do the substitutions

anonymous · Answer

C = (F -32)5/9
75-49 = 26 F = (26-32)5/9 C

anonymous · Answer

what cinar said 
$$\frac59 (49-32)=C$$ and 
$$\frac59 (75-32)=C$$ and compare those two
