Solve for x.
x+1/2=3/4
a) x=1/4
b)-1/4
c)-1/2
d)1/2

Solve for x (get x by itself)

    Subtract 1/2 on both sides

 Make the denominators the same to combine them, so you multiply 2 to the top and bottom of 1/2 to get 2/4

Your answer is A

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
