Answer:

<h2>3x = 18</h2>

Step-by-step explanation:

Use the Pythagorean Theorem here:

30² = (3x)² + (4x)², or:

30² = 9x² + 16x²  =  25x²

Taking the square root of both sides, we get √(30)² = √(25x²), or:

30 = ± 5x

Neglect -5x, since we are measuring distances, and distances are positive.

Then 5x = 30, and so x = 6

Thus, 3x = 3(6) = 18

Answer choice <br> D) A worker with 15 years of service gets 5 weeks of vacation and each year.
otez555 [7]

Answer: it seems to be D, but the equation makes practically no sense!

The value of the factor changes for the different amounts of service years and vacation weeks.

Step-by-step explanation: The equation means that the employee is trying to figure out the value of the "v-factor" for how vacation time is earned.

If you substitute the number of service years into the left side of the "formula" and vacation weeks on the right side, then solve for "v", v(15)=5 you get v= 1/3 or 0.33

If you substitute other numbers, like v(2)=2, so v= 1 then v(30) = 8, v = 4/15 or 0.2667. You see the factor's value decreases. The company is much more generous to to employees with one or two years of service than with the older ones.
