Answer:

4x + 10 = 30

Step-by-step explanation:

The four unknown pieces of rope are said to be an equal length, so each piece will be represented by x. Now there is another 10 feet of rope that is attached, and that all together equals 30 feet. The equation is:

4x + 10 = 30

4x = 20

x = 5

(I'm so sorry I can't draw a diagram for you, but I hope you will be able to using the equation shown above!)

Vinil7 [7]
This employee who was randomly chosen represents the population of the company. This means that, any parameter measured through this employee can be considered as the mean or average value for the whole population (the company).

Based on this, taking the age of the employee as the desired parameter, the age of this employee will be considered as the average or mean age for the whole company. This means that the age of the employee and the mean age of all employees are equal.

Therefore, the answer is C) 32, 32

The value of x equals 30.

Step by Step explanation:

All sides are equal so you know the angle lengths are equal. When you multiple 2x by 3 you get 6x. All angles of a triangle add up to 180 so you divide 180 by 6 and you get 30. Hope This Helps!
