Sabrina has a rug with a perimeter of 18 feet. she decides to place a border around the rug so that the new length of the rug is 8 feet and the width is 4 feet. the border is the same width all the way around. the equation which represents x, the width of the border is 2(8-2x)+ 2(4-2x)=18. what is the width of the border?

a. 3/4

b. 1 1/2

c. 1 ft

d. 3 ft

The answer is: a.

Since we are given the equation which represents the width of the border (x) we only need to isolate the variable (x), so:

So, the width of the border is:

Have a nice day!

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
