If 3 is added to a number and the sum is tripledtripled, the result is 27 more than the number. find the number.

To solve this problem, let us say that the number is called x and let us do this step by step.

1st step: 3 is added to the number, therefore:

x + 3

2nd step: the sum is tripled, therefore:

3 (x + 3)

3rd step: the result in the 2nd step is equal to 27 more than the original number, therefore:

3 (x + 3) = x + 27

4th step: find for the value of x using the equation

3 x + 9 = x + 27

3 x – x = 27 – 9

2 x = 18

x = 9

The number is 9

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
