Answer:

  • Zero

Step-by-step explanation:

Step 1. Find the mean

  • (- 9 - 18 - 16 - 13 - 14)/5 = - 14

Step 2. Find the deviation of each value from the mean

  • - 9 - (- 14) = 5
  • - 18 - (- 14) = - 4
  • - 16 - (- 14) = - 2
  • - 13 - (- 14) = 1
  • - 14 - (- 14) = 0

Step 3. Find the sum of the deviations

  • 5 - 4 - 2 + 1 + 0 = 0

Step 4. Find the MAD

  • 0/5 = 0

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

3(x - 2) = 2(x + 1)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute:                                     3x - 6 = 2x + 2
  2. Subtract 2x on both sides:          x - 6 = 2
  3. Add 6 to both sides:                    x = 8

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    3(8 - 2) = 2(8 + 1)
  2. Subtract/Add:                      3(6) = 2(9)
  3. Multiply:                               18 = 18

Here we see that 18 does indeed equal 18.

∴ x = 8 is a solution to the equation.
