It would be P-2W/2=L. Basically you just move everything away from the variable you want to isolate. Good luck! :D
Answer:
x=4, y=13. (4, 13).
Step-by-step explanation:
3x+2y=38
-6x+4y=28
----------------
simplify -6x+4y=28 into -3x+2y=14
-------------------------------------------------
3x+2y=38
-3x+2y=14
------------------
4y=52
y=52/4=13
3x+2(13)=38
3x+26=38
3x=38-26
3x=12
x=12/3=4
x=4, y=13.
Answer:
<u>∠AEB = 72°</u>
Step-by-step explanation:
<u>Finding x</u>
- ∠AEB = ∠DEC (Vertically opposite angles)
- 7x - 5 = 2(4x - 8)
- 7x - 5 = 8x - 16
- 8x - 7x = -5 + 16
- x = 11
<u>Finding ∠AEB</u>
- 7x - 5
- 7(11) - 5
- 77 - 5
- <u>∠AEB = 72°</u>
PV = P(1 - (1 + r)^-n) / r; where P is the periodic withdrawal = $100,000; r = rate = 5% = 0.05; n = number of periods = 20 years.
PV = 100000(1 - (1 + 0.05)^-20) / 0.05 = 100000(1 - 1.05^-20) / 0.05 = 100000(1 - 0.3769) / 0.05 = 100000(0.6231) / 0.05 = 100000(12.4622) = 1,246,221 ≈ $1,250,000
