Point S is on line segment RT. Given RT = 3x, RS = 3x - 5, and ST = 3x - 1, determine the numerical length of RT.

LETS TAKE AS R-S-T

d(rt)=d(rs)+d(rs)

3x=3x-5+3x-5

3x=(3x+3x) (-5+-5)

3x=(6x)x(10)

3x=60

x=60/3

x=20

d(rt)=20 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.
