Answer:
x is undefined
Step-by-step explanation:
2 + 6(x - 4) = 3x - 18 + 3x
Open the bracket
2 + 6x - 24 = 3x - 18 + 3x
collect the like terms
6x -3x - 3x = -18 +24 - 2
0x = 4
x = 4/0
x is undefined
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.
