Use the order of operations to evaluate the expression 4 x (3/4-1/2) + 3 x 6

19

Step-by-step explanation:

19

Step-by-step explanation:

change 1/2 to 2/4

then do 3/4 minus 2/4 which equals 1/4

4 times 1/4 equals 1

3 times 6 equals 18

1 plus 18 equals 19

answer: 193

explanation:

200-7 = 193

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
