By viewing equivalent ratios and rates as deriving from, and extending, pairs of rows (or columns) in the multiplication table and by analyzing simple drawings that indicate the relative size of quantities.
3(0) = 2x + 6
( 0 = 2x + 6 ) - 6
( -6 = 2x ) /2
x = -3
The answer is B. (-3, 0).

The associative property allows you to change the <em>grouping</em> of addends or factors without changing the value of the expression.
Answer:
![Probability = \frac{3}{7}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B3%7D%7B7%7D)
Step-by-step explanation:
Given
Electrician = 6
Mechanic = 8
Required
Determine the probability of selecting an electrician
First, we need the total number of employees;
![Total = n(Electrician) + n(Mechanic)](https://tex.z-dn.net/?f=Total%20%3D%20n%28Electrician%29%20%2B%20n%28Mechanic%29)
![Total = 6 + 8](https://tex.z-dn.net/?f=Total%20%3D%206%20%2B%208)
![Total = 14](https://tex.z-dn.net/?f=Total%20%3D%2014)
Next, is to determine the required probability using the following formula;
![Probability = \frac{n(Electrician)}{Total}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7Bn%28Electrician%29%7D%7BTotal%7D)
![Probability = \frac{6}{14}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B6%7D%7B14%7D)
Divide numerator and denominator by 2
![Probability = \frac{3}{7}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B3%7D%7B7%7D)
<em>Hence, the probability of selecting an electrician is 3/7</em>
