Question

A food scientist uses a mixture of the gases helium and argon to preserve packaged food. The amount of

each gas the scientist uses for the mixture is modeled by the equation 5.6H + 0.56A = 22.4, where H and A
are the masses, in grams, of helium and argon, respectively. If the scientist uses 10 grams of argon, how
many grams of helium are used?
PLEASE HELP!

Answer 1

H is 16.8

Explanation:

If you multiply 5.6 times 3 you get 16.8 and then you add 5.6 because 0.56 times 10 equals 5.6
