1 answer

Let's solve each problem step by step:

  1. For the equation: 16 + -22 =

    • This can be simplified as \( 16 - 22 = -6 \).
    • Answer: -6

  2. For the equation: -36 + -10 + 6 =

    • First, calculate \( -36 + -10 = -46 \).
    • Then, \( -46 + 6 = -40 \).
    • Answer: -40

  3. For which subtraction expression has the same difference as -10 - 3?

    • The expression \( -10 - 3 = -13 \).
    • We need to find another expression that also equals -13.
      • \( -13 - 4 = -17 \) (not equal)
      • \( -4 - 13 = -17 \) (not equal)
      • \( -4 - 9 = -13 \) (equal)
      • \( 4 - 9 = -5 \) (not equal)
    • Answer: -4 - 9

  4. For the temperature problem: The temperature is 5 degrees at dusk. It is 8 degrees colder at dawn. What is the temperature at dawn?

    • If it is 5 degrees at dusk and it is 8 degrees colder, that can be calculated as \( 5 - 8 = -3 \).
    • Answer: -3

Here are the summarized answers:

  1. -6
  2. -40
  3. -4 - 9
  4. -3
