N=199 because in order to get a a smaller negative you would have to add a positive into a negative
1/7 gallon = 1 batch
<em>[multiply by 7 through]</em>
1 gallon = 7 batches
<em>[multiply by 8/9 through]</em>
8/9 gallon = 7 x 8/9
8/9 gallon = 6 2/9
<em>[Good enough to make 6 batches, not enough to make 7 batches]</em>
So he can make 6 batches of collard green
I think your supposed to add them all together or divide
P = 2(l + w)
p = 356
l = 96
356 = 2(96 + w)
356 = 192 + 2w
356 - 192 = 2w
164 = 2w
164/2 = w
82 = w
check....
p = 2(l + w)
356 = 2(96 + 82)
356 = 2(178)
356 = 356 (correct)
so the width (w) = 82 cm
We divide by 2 on both sides.
We get the final answer as
x = 5/2 = 2.5
