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
