Write the following phrase as an algebraic expression and simplify Four-sevenths of a number, increased by fifteen
The answer is
(Simplify your answer.)

4/7n+15

Step-by-step explanation:

Let the number be n

4/7 of a number means: 4/7 times a number (n). So 4/7n then, increase (add) that by 15

you'll get the equation 4/7n+15

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
