Devin is 1 1/4 younger than eli. april is 1/5 as old as devin. jill is 5 years older than april. if eli is e years old what is jill's age in terms of e?

Step-by-step explanation:  

We have been given that Eli is E years old.

Devin is 1 1/4 younger than Eli, therefore, Devin's age in terms of E will be:

Further we are told that April is 1/5 as old as Devin. So April's age will be,

Upon simplifying our expression we will get,

Now let us write Jill's age in terms of E.

We are told that Jill is 5 years older than April. So Jill's age will be,

Therefore, Jill's age in terms of E will be .

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.
