X: y = 5:3 and x+ y=56
Work out the value of x-y

14

Step-by-step explanation:

Given: x : y = 5: 3

Therefore, let x = 5a and y = 3a

x + y = 56

5a + 3a = 56

8a = 56

a = 56/8

a = 7

x = 5*7 = 35

y = 3*7 = 21

Therefore,

x - y = 35 - 21 = 14

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.
