Sam has a total of 40 dvds, movies and tv shows. the number of movies is 4 less then 3 times the number of tv shows. write and solove a system of equations to find the number of movies and tv shows.

Sam has 29 movies.

Sam has 11 TV shows.

Step-by-step explanation:

Let x represent the number of movies that Sam has.

Let y represent the number of TV shows that Sam has.

Sam has a total of 40 dvds, movies and tv shows. This means that

x + y = 40 - - - - - - - - - - -1

The number of movies is 4 less then 3 times the number of tv shows. This means that

x = 3y - 4 - - - - - - - - - - -2

Substituting equation 2 into equation 1, it becomes

3y - 4 + y = 40

4y - 4 = 40

4y = 40 + 4 = 44

y = 44/4 = 11

x = 3y - 4 = 3 × 11 - 4

x = 33 - 4

x = 29

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

r = 78539458390583095803458309458039485093485 or just 3
