-18 - 30 = -48
The Scuba Diver is now 48 feet below sea level.
The number in question is equal to 2 times the temperature in degrees Celsius.
<h3><u>Equations</u></h3>
Since Alisha is working on a project about temperature conversion in her science class, and the formula for converting degrees Celsius to degrees Fahrenheit is F=C+32, to solve FC + 32 the following equation must be performed:
- CF + 32 = X
- F + F + 32 + 32 = X
- 2F + 64 = X
- F + 32 = 1/2X
- X = 2C
Therefore, the number in question is equal to 2 times the temperature in degrees Celsius.
