129 lbs and 5'5" gives a BMI of 21.47 which is normal.
The normal weight range of the given heigh is 111 - 150 lbs.
Please see the related link for the calculation.
55 + x = 180 x = 180 - 55 x = 125
15% of 55 pounds= 15% * 55= 0.15 * 55= 8.25 pounds
125-180 = -55
A 145 pound person would weigh approximately 55 pounds on Mars due to the lower gravity on the planet compared to Earth.
125 + 55 = 180
t + 98 + 55 = 180 t + 153 = 180 t = 180 - 153 t = 27
55 pounds is 24,947.58 grams
At 5'3" you ideal BMI would be under 141 pounds. http://www.nhlbisupport.com/bmi/ You can key in your weight and height here. I would say 110 is good for the lower end. So between 110 and 140 is good. The answer is not based on age, so if you are the upper end of the range it is fine. I'm 55 too and was looking for specific BMI for our age ...and have not found them yet.
(1 kg = 2.2046 pounds) > 55 kgs = 55 * 2.2046 = 121.25 pounds
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
180
20/100*55=.2*55=11 pounds
