Let's start with the length. All you need to do is multiply is by 1/500.
You could also find the decimal equivalent to 1/500.
1/500= .002
200×.002= .4
So length of the model is .4 ft.
The width:
.002×140=.28
The width of the model is .28 ft.
The length of the model is .4 ft and the width of the model is .28 ft.
The correct answer is 2.86
2x≤4
I'm not sure how else to help you in this situation, without you providing me with more information. If you want the solution for x, you would just divide both sides by the coefficient of the variable, or 2, resulting in the inequality:
x ≤ 2
Hope this helps! Comment if you need to add info or have any more questions about this problem.
Answer: The formula for exponential growth is y = a(1 + r)^x, and the formula for exponential decay is y = a(1 - r)^x, with r being the rate of growth/decay. :)
