Movie mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a dvd. hurricane video is free to join, but dvds cost $6.00 to rent. write and solve an equation to find the number of dvds you would have to rent in order for both stores to charge the same. explain what your variable represents. a. let n = the cost of renting a movie; 20n + 4 = 6; 40 videos b. let n = the number of dvds rented; 20 + 4n = 6n; 10 videos c. let n = the cost of renting a movie; 20n + 4 = 6; 2 videos d. let n = the number of dvds rented; 20 + 4n = 6n; 40 videos

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

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
