360/20 is equal to 18 sides
If the gray suitcase weighs 11 lb more than the pink suitcase, the pink suitcase weighs 5 lb than the blue suitcase, and the total of 3 suitcases is 127 lb, then the blue suitcase weighs 35.3 lb
Let the gray suitcase be represented by g
Let the pink suitcase be represented by p
Let the blue suitcase be represented by b
The gray suitcase weighs 11 lb more than the pink suitcase
g = p + 11........(1)
The pink suitcase weighs 5 lb than the blue suitcase.
p = b + 5
b = p - 5...........(2)
Total of 3 suitcases = 127 lb
p + b + g = 127............(3)
Substitute equations (1) and (2) into equation (3)
p + p - 5 + p + 11 = 127
3p + 6 = 127
3p = 127 - 6
3p = 121
p = 121/3
p = 40.3 lb
Substitute p = 40.3 into equation (2)
b = p - 5
b = 40.3 - 5
b = 35.3
The blue suitcase weigh 35.3 lb

Answer:
36.695 approx 36.7
Step-by-step explanation:
find the area of the top triangle and then add it to the area of the bottom rectangle
Area of the triangle: (bh)/2
3.5*4.1=14.35
14.35/2=7.175
Area of the rectangle: bh
4.1*7.2=29.52
Total (add the two values)
29.52+7.175
=36.695
Interest rate i=19.1% compounded annually.
Initial deposit, P=48900
Time t=53 months=53/12 years
Use compound interest formula
Future value,
F=P(1+i)^(t)=48900(1+0.191)^(53/12)
= $105,824.40 (to the nearest cent)
