Answer:
l = 20
Step-by-step explanation:
set up a system of equations
l = 3w -1
54 = 2l + 2w
substitute
54 = 2(3w-1) + 2w
56 = 8w
w = 7
l = 3 *7 -1
x = 19 cm
3+3+2+5+6 = 19
A number decreased by three squad is a nonlinear.
17,900 x 0.1296 = 2318.05
2318.05 should be subtracted from 17,900 and it should be somewhere around 15,581.95
