Question 111253: How do you wright an equation for this problem?:
You are designing a house with three 3-feet wide windows on the back of the house. There are 4 feet between each end window and an edge of the house. The width of the house is 33 feet. How far apart should the windows be?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
(3 x width of a window) + (2 x distance to edge of house)
+ (2 x separation of windows) = 33'
---------------------------------------------------------
(2 x separation of windows) = 33 - (3 x width of a window)
+ (2 x distance to edge of house)
---------------------------------------------------------
(separation of windows) = (1/2)*(33 - (3 x width of a window) - (2 x distance to edge of house))
---------------------------------------------------------
separation of windows = (1/2)*(33 - 3*3 - 2*4)
separation of windows = (1/2)*(33 - 9 - 8)
separation of windows = (1/2)*16
separation of windows = 8' answer
------------------
check
(3 x width of a window) + (2 x distance to edge of house)
+ (2 x separation of windows) = 33'
3*3 + 2*4 + 2*8 = 33
9 + 8 + 16 = 33
33 = 33
OK
