lol. I have finished plenty of studies that required a great degree of commitment to learning. My time is valuable, and I see no point in spending it on something that I might have not much use for later.

the PMP course requires expert Excel knowledge?:eek:

You can start being concerned. I could not make one myself :)

Yes but it's not about "that person" really - it's about hundreds of people who will see this post when they search for something online. Can you imagine how many people came here in 10 years? And this thread will be here for another X years. I tried following a few tutorials online, and I must...

yes sir

Who cares if it's as relative today as it was 10 years ago?

I am very new to project management, as a matter of fact am soon to become a student member of PMI. This all might look easy to you - just google and take any search result but that's exactly where the issue is. There are so many results, and they are all so different... sometimes you just...

x + 5y = -13 --- (1) 2x - y = 7 --- (2) From eq. (2) y = 2x - 7 --- (3) Putting this value of y in eq. (1) x + 5(2x -7) = -13 x +10x - 35 = -23 11x = -13+35 11x = 22 x = 22/11 x = 2 ----- (A) Putting x = 2 in (3) y = 2(2) - 7 y = 4 - 7 y = -3 -----(B)

I stumped on it too :rolleyes:. Do share the answer if you have by now - I am curious to know :)

C: 28%

Yes, thank you. This is really a comprehensive support.

Both answers are correct - one is in degrees and the other one is in decimal.

Yeah, 16 years ago - It's always great to look at our achievements that we made years ago :)

Congratulations on being on top! :angel:

( 2x-1)/5 = (x/3) -1 5[( 2x-1)/5] =5[(x/3) -1] 2x - 1 = 5(x/3) - 5 2x - 1 = 5x/3 - 5 3(2x - 1) = 3(5x/3 - 5) 6x - 3 = 3(5x/3) - 3(5) 6x - 3 = 5x - 15 6x - 5x = -15 + 3 x = -12

Q1. (x + 5)(x - 4) = 0 Solution: x + 5 = 0 OR x - 4 = 0 x = -5 OR x = 4 Q1. x² - 8x + 15 = 0 x² - 5x - 3x + 15 = 0 x(x - 5) -3(x - 5) = 0 (x - 5)(x - 3) = 0 (x - 5) = 0 OR (x - 3) = 0 x = 5 OR x = 3

Seems as two steps are missing. My solution is: y^2/5 - 2 = 18 y^2/5 = 20 y^2 = 5*20 y^2 = 100 y = +- square root(100) y = +-10

Seems an asset playlist - Thank you for the effort!
