___ + 8 = 0 -6 + ___ = negative number ___ - (-8) = positive number

1 answer

To solve the equations and fill in the blanks, let's analyze each statement one by one:

  1. ___ + 8 = 0: To make this statement true, we need to find a number \( x \) such that: \[ x + 8 = 0 \] Subtracting 8 from both sides gives us: \[ x = -8 \] So the first blank must be -8.

  2. -6 + ___ = negative number: We need to determine a number \( y \) such that when added to -6, the result is still a negative number. For this to happen, \( y \) must be less than 6 (since \(-6 + 6 = 0\), which is not negative). Thus, \( y \) must be any number less than 6.

    So, possible responses for this blank are any number less than 6. Examples include: -7, -10, -1, 0, etc.

  3. ___ - (-8) = positive number: This statement simplifies to: \[ z + 8 = \text{positive number} \] For this result to be positive, \( z + 8 > 0 \) must be true, which means: \[ z > -8 \] Thus, the third blank can be any number greater than -8. Examples include: -7, 0, 1, 5, 10, etc.

Summary of the Responses:

  • The first blank is -8.
  • The second blank can be any number less than 6 (e.g., -7).
  • The third blank can be any number greater than -8 (e.g., -7 or 0).

When filling in the blanks, sample responses could be:

  1. -8
  2. -7 (or any number < 6)
  3. 0 (or any number > -8)

Feel free to choose from the examples given for the second and third blanks as applicable.
