Mrs. washington's class has x student. Three-fourths of these students like pizza. If 21 students in the class like pizza, which equation can be solved to determine the number of students in the class? A. 21x = 3/4
B. 21x = 4/3
C. 4/3x = 21
D.3/4x = 21

the answer is C .4/3=21

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
