The partial blueprint of a house that includes 3 bedrooms is shown below. The scale is 2.75 inches : 3 feet. What is the actual length and width of Bedroom 3 in feet?
Bedroom 1 w=9.17; l= 11 in
Bedroom 2 w=7.33 in; l= 12.83
Bedroom 3 w= 11 in; l= 14.67 in

___________
2.75 inches : 3 or 2.75 in / 3 feet

Can you see the updates?
______________
Bedroom 3 w= 11 in; l= 14.67 in
11 in * 3 feet / 2.75 in = 12 feet
14.67 in 3 feet / 2.75 in = 16 feet

Answer
Bedroom 3 w= 12 ft ; l= 16 ft
Answer:
w=5
Step-by-step explanation:
using the distributive property to simplify the equation
-4(w)+1(-4)=-24 so
-4w-4=-24 (adding 4 to both sides)
-4w==20 (divide by -4)
w=5
Answer:
2. Since it is equilateral, we just set up an equation with using any two sides (since they are all equal)
12x - 22 = 10x - 6
12x - 10x - 22 = -6
2x - 22 = -6
2x = 22 - 6
2x = 16
x = 16/2
x = 8
Each side = 74
3. Same formula for this. Get any two sides and setup the equation.
4x - 25 = x + 14
4x - x - 25 = 14
3x = 25 + 14
3x = 39
x = 39/3
x = 13
Each side = 27
4. This one is also simple. Since DE = EF. We substitute its sides with the equations.
8x - 13 = 5x + 17
8x - 5x - 13 = 17
3x - 13 = 17
3x = 17 + 13
3x = 30
x = 30/3
x = 10
DE and EF = 67
DF = 31
