Bella works at a shoe store. in addition to a fixed salary, she earns a commission for each pair of shoes that she sells. the table shows bella’s total earnings , y (in dollars), from selling x pairs of shoes: shoe sales and earnings pairs sold (x) total earnings (y)
x y
1 95
2 110
3 125
which equation best shows the relationship between x and y?

a.) y = x + 80
b.) y = 15x + 95
c.) y = 15x + 80
d.) y = x + 95

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
