Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating
__________________
90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
D)30 us 6 times as many as 5 and 5 times as many as 6.
Ok here you all you need to find is you equation hinting towards the points stated on the graph. Graphing has never been my strong suit, but I can assure that your answer would be:
D: 8 = -4y - 3x
The answer is:
50(16n+21)
