Felix measured a house and its lot and made a scale drawing. he used the scale 1 inch : 8 feet. if the porch is 2 inches in the drawing, how wide is the actual porch?

16 feet wide

Step-by-step explanation:

Use the proportion

1 in is to 8 feet as 2 inches is to 'x' feet.

1/8 = 2/x    

now solve by cross multiplying

x = 16 feet

10.4 inches

step-by-step explanation:

2x2x2.6

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
