Captured carbon dioxide can be used for different purposes. food and beverage companies use 4 million metric tons (mmt) of carbon dioxide per year, which is 6% of all captured carbon dioxide. enhanced oil and natural gas recovery uses 88% of all captured carbon dioxide. create a formula where x = the amount of carbon dioxide used for enhanced oil and natural gas recovery. solve for x. the amount of co2 used for enhanced oil and natural gas recovery is mmt.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
