82 X 10-6 glm3of pollutants in the air. ... The weight of 1m3 of air is approximately 1.3 X 103g.Suppose that the volume of air inside of a building is 3 x 106 m3.
Answer:
vertical and horizantal
Step-by-step explanation:
You can solve this by multiplying each numerator by the answer choices and trying to divide them. I can't get the fraction maker to work at the moment, so I'll write the calculations on a separate attachment.
As you can see, the only choice that works to eliminate both fractions is the fourth choice,
50x.
Simplify it to 2x-4=8x-4
-6x=0
x=0
not sure if that counts as no solution or single solution though...
14 ÷ 1/2 × 3 (I hope it's right. I would have done this)
