Will ! one month ivanna rented 8movies and 3 video games for a total of $51 . the next month she rented 2 movies and 5 video games for a total of $34 . find the rental cost for each movie and each video game.

8m+3v=51

2m+5v =34

multiply the 2nd equation by -4

-8m -20v = -136

add 1 and the modified 2nd equation together

8m+3v=51

-8m -20v = -136

-17v = -85

divide by -17

v=5

substitute into 1st equation

8m+3v=51

8m +3(5) = 51

8m +15 = 51

subtract 15 from each side

8m =36

m =4.5

videos are $5.00

movies $4.50

8

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
