What inequality is one fourth of the opposite of the difference of five and a number is less than 20

n < 85

Step-by-step explanation:

1/4(-5+n) < 20 the opposite of 5-n is -5+n

multiply by 4

-5 + n < 80

+ 5

= n < 85

2 5/8 is the final answer! : )

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
