Assuming you mean the area is 28 yd², equations for the length (y) and width (x) can be written:
These equations can be solved by a variety of means. One I like is graphing. A graphing calculator tells you the solution is (width, length) = (3.5 yd, 8 yd).
-- If it's only the ' 8 ' that repeats forever,
then that decimal is equivalent to 53/90 .
-- If the ' 58 ' repeats forever, then
the decimal is equivalent to 58/99 .
10 minus 9 would be 1 and 1 plus 8 is 9 so your answer is 9!!!
Well to isolate the variable you should subtract 6 from both sides resulting in -4y > 16
Now just divide by -4, however, keep in mind that when you divide or multiply by a negative number when there is a sign, always switch the sign, so just divide by -4 and get y < 4
