The length of a rectangle is 5 centimeters less than twice its width. the perimeter of the rectangle is 80 cm. what are the dimensions of the rectangle? length = 25 cm; width = 15 cm length = 24 cm; width = 16 cm length = 23 cm; width = 14 cm length = 22 cm; width = 18 cm

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
