Answer:
7.5
Step-by-step explanation:
28! hope this helps, you just plug in 4 for x, and then multiply by two.
Answer:
A) L = 2*W
B) 2L + 2W = 42
We'll put Equation A) into B)
2*2W + 2W = 42
4W + 2W = 42
6W = 42 cm
Width = 7 cm
Length = 14 cm

Answer:
Step-by-step explanation:The model will be of length 0.4 ft and the width being 0.28 feet
Step-by-step explanation:
Step 1.We know that the length of the building is 200 feet, and that the width of the building is 140 feet.
Step 2. the question tells us that "a 1/500 model is built of the building", meaning the problem wants to create a model using the ratio 1 feet for each 500 feet.
Step 3.So now to find the length and width of the model, we need to divide the given sides by 500.
Step 4. Side length of the Model = 200/500 = 2/5 = 0.4 feet
Step 5. Side width of the Model = 140/500 = 14/50 = 0.28 feet
There for giving us our final answer... "The model will be of length 0.4 feet and width 0.28 feet."
Hope I could help! :)
