Answer:

Step-by-step explanation:

Equation

2(x + 4) = x - 1

Solution

2x + 8 = x - 1                Subtract x from both sides

2x-x + 8 = - 1                Combine the left

x + 8 = - 1                     Subtract 8 from both sides

x + 8-8 = - 1-8

x = - 9

Check

<em>LHS</em>

2(-9 + 4)

2(- 5)

-10

<em>RHS</em>

-9 - 1

- 10

1. MAD for Jada's data set = 1

Step-by-step explanation:

Mean Absolute Deviation = sum of the distances of each data value from the mean ÷ number of data value

Jada's data set is given as: 4, 4, 4, 6, 6 ,6

Mean = 5

✔️Find the distance between each data value form the mean

4 = |4 - 5| = 1

4 = |4 - 5| = 1

4 = |4 - 5| = 1

6 = |6 - 5| = 1

6 = |6 - 5| = 1

6 = |6 - 5| = 1

✔️Find the sum of the distances of each data value from the mean

1 + 1 + 1 + 1 + 1 + 1 = 6

✔️Find the MAD:

MAD = 6/6

MAD = 1
