To answer this question you have to find the lowest common multiple of 10 and 12. The lowest common multiple of 10 and 12 is 60 so therefore they need to sell 60 packs to get the same number.
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.

Answer:
Dennis skated 35/4 of track in two minutes.
35/4 = 8 3/4
Step-by-step explanation:
Given that;
Daniel skated 2 1/2 of the way around the track in two minutes
Daniel = 2 1/2 = 5/2 of track
her younger brother skated 3 1/2 of Daniels distance in two minutes
Dennis = 3 1/2 of Daniel's = 3 1/2 of 5/2
Dennis = 3 1/2 × 5/2 = 7/2 × 5/2
Dennis = 35/4 = 8 3/4
Therefore, Dennis skated 35/4 of track in two minutes.
