What’s the answer to 14?

Answer:

  • |t -(-5)| = 1.5
  • [-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

  |t -(-5)| = 1.5

This is equivalent to two equations:

  • t +5 = -1.5
  • t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

  • t = -6.5 . . . . minimum allowed temperature
  • t = -3.5 . . . . maximum allowed temperature
