How do you simply 5/2(6x-7)+4/3(2+9x)

27x+−89/6

Step-by-step explanation:

Let's simplify step-by-step.

5/2(6x−7)+4/3(2+9x)

Distribute:

=(5/2)(6x)+(5/2)(−7)+(4/3)(2)+(4/3)(9x)

=15x+−35/2+8/3+12x

Combine Like Terms:

=15x+−35/2+8/3+12x

=(15x+12x)+(−35/2+8/3)

=27x+−89/6

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.
