The answers is 2:10 or 2/10
Let the original amount be A. Double that would be 2A.
Then, 2A = Ae^(r*5), or 2 = e^(5r).
Taking the natural log of both sides: ln 2 = 5r. Then r = (ln 2)/5 = 0.14
The interest rate would have to be 13.86% per year, written here as r=0.14.
2x + 5 > 9 and 5x ≤ 30
- 5 - 5 5 5
2x > 4 x ≤ 9
2 2
x > 2
Solution Set: {2 < x ≤ 9}, (2, 9]
116+y=180(sum of angles in a straight line)
y=180-116
y=64
x+y+125+72=540(sum of angles in a quadrant)
x+64+125+72=540
x+125+136=540
x+261=540
x=540-261
x=79
