First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2

Answer:
118.75
Step-by-step explanation:
The mean is all of the numbers added up and then divided by the number of numbers. Example: 1+1+1 number of numbers: 3. 1+1+1=3. 3÷3=1. In this case, it would be 102+124+140+130+120+110+124+100=950. The number of numbers is 8, so you would go 950÷8. Then you would get an answer of 118.75. I hope I helped!
