A blueprint for a house shows a bedroom being 5.5 inches wide. The scale used to create the blueprint is 0.50 in. = 1 ft. What is the actual width of the bedroom?

Set up a proportion and cross multiply.

0.5/1 = 5.5/x
0.5x = 5.5
x = 11 feet

I dont know how to do this

A blueprint for a house shows a bedroom being 5.5 inches wide. The scale used to create the blueprint is 0.50 in. = 1 ft. What is the actual width of the bedroom?

Well, that's one cozy bedroom! According to the scale of 0.50 in. = 1 ft, if the bedroom on the blueprint is 5.5 inches wide, then in real life it would be (drumroll, please...) 11 feet wide! Time to do some furniture shopping, because that's a lot of space!

To find the actual width of the bedroom, we need to convert the dimension on the blueprint to the corresponding dimension in real life.

Given:
Width of the bedroom on the blueprint = 5.5 inches
Scale used on the blueprint = 0.50 in. = 1 ft

Step 1: Convert the blueprint width to feet.
Since 0.50 inches on the blueprint represents 1 foot in real life, we can set up a proportion:

0.50 inches (on the blueprint) / 1 foot (in real life) = 5.5 inches (on the blueprint) / x feet (in real life)

Cross-multiplying, we get:
0.50 inches * x feet = 5.5 inches * 1 foot

Step 2: Solve for x.
0.50x = 5.5
Divide both sides of the equation by 0.50 to isolate x:
x = 5.5 / 0.50
x = 11

Therefore, the actual width of the bedroom is 11 feet.
