You are interested in purchasing a widescreen television set at Target. On this type of TV, the ratio of screen width to screen height is 16 to 9. If a certain model you are considering has a screen width of 48 inches, what is the height of the screen
height = x
width = y
=> 16/9 = y/x
16x = 9y => x = 9y/16 (1)
y = 48 (2)
from (1), (2)
=> x = 9*48/16 = 27
=> height = 27 in
