Basic equation 4x + 45 = 89. To solve for x, What do you do first? A. add 45 on both sides
B. subtract 45 on both sides
C. subtract 89 on both sides
D. add 89 on both sides

B.

Step-by-step explanation:

Subtract 45 from both sides first. Then divide by 4.

Subtract 45 from both sides to eliminate that number

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
