Assuming the legislature consists of more than 17 members, the 17 constitute a SAMPLE.
I think that the answer is X=2/7. I hope this helps!!! :)
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
The lowest common multiple of 12 and 27 is 108.
12 x 9 = 108 and
27 x 4 = 108 .
So she has to buy 9 packs of cards ... 108 of them ... and 4 packs of envelopes.
