Will mark brainliest!

i need a little filling this out

you : )

2. 3x = 5x - 20

3. -2x = -20

Step-by-step explanation:

First you just have to the 5 * x and 5*4

Then you have to subtract 5x from both sides to get x on its own

Hope I helped

3x=5x-20 Distributive

3x=5x-20

    -5x

-2x= -20

Step-by-step explanation:

Hope this helps :))

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

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
