The sum of two numbers is 5. The difference of the numbers is -15. Find both numbers.

-5 , 10

Step-by-step explanation:

x be  on number

The other number = 5 - x

x - ( 5- x) = -15

x - 5 + x = -15

2x = -15 + 5

2x = -10

x = -10/2

x = -5

One number =  -5

The other number = 5 - x  = 5 - (-5) = 5 + 5 = 10

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
