The width of scale drawing is 4 inches
Step-by-step explanation:
The length of room =L1= 18 ft
The width of room =W1= 12 ft
The scale drawing length=L2 = 6 inches
The scale drawing width W2= x
According to rule of three

putting values in equation we get


Re-arranging the equation we get

So the width of scale drawing is 4 inches

Answer:
The first one is -1/2
the second one is x+2y-27=0
The answer C make more sense.
Find the slope of the line through (x1,y1) = (0,6) and (x2,y2) = (2,0)
m = (y2 - y1)/(x2 - x1)
m = (0 - 6)/(2 - 0)
m = -6/2
m = -3
The slope is -3
Since we're given the point (0,6) to be on the line, we know the y intercept is b = 6.
Plug m = -3 and b = 6 into y = mx+b to get y = -3x+6
Answer: Choice D) y = -3x+6
I think that x=9 not sure though
