- B is the midpoint of line segment AC. If AB = 3x - 8 and BC = x + 12, find the value of x.

x = 10

Step-by-step explanation:

Since B is the midpoint, segment AB and segment BC are equal to each other

3x - 8 = x + 12

Subtract x on both sides.

2x - 8 = 12

Add 8 to both sides

2x = 20

Divide by 2 on both sides

x = 10

x = 10

Step-by-step explanation:

Since B is the midpoint of segment AC, then AB = BC.

AB = BC

3x - 8 = x + 12

2x - 8 = 12

2x = 20

x = 10

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
