Solve 4x - 9 = 15 a. one and one half b. 6 c. 8 d. 24 i’m pretty sure it’s d. i’m just looking for other

4x - 9 = 15

Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)

4x = 24

Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)

x = 6

The answer is B

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
