X+100+(X+12)=180. solve for x

-10.099009901

Step-by-step explanation:

X+100+(X+12)=180

multiply the numbers in (  ) by 100 to get

X+100X+1200=180

add the x to the 100x

101X+1200=180

       -1200   -1200

subtract 1200 from both sides

101x=-1020

divided

-1020/101

X=-10.099009901

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
