Answer:
-1.8 =x
Step-by-step explanation:
12(x+3)=-8x
Distribute
12x +36 = -8x
Subtract 12x from each side
12x-12x +36 = -8x-12x
36 = -20x
Divide each side by -20
36/-20 = -20x/-20
-9/5 = x
Changing to decimal form
-1.8 =x

SashulF [63]
Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, mean = 73/10
Mean = 7.3
