Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
A. x = 3, y = 2, z = 5, w = 5; (3, 2, 5, 5) B. x = -6, y = 29, z = -36, w = -24; (-6, 29, -36, -24) C. x = 2, y = 4, z = 1, w = 7; (2, 4, 1, 7) D. x = 3 + w, y = 2 - 2w, z = 5 + 2w, where w is any real number
Mike and Tom divide a pizza that is one-half vegetarian and one-half not. Determine the false statement.
a. Only Tom is a vegetarian. If the pizza is cut into such a way that both parts have a half of vegetarian and a half of not vegetarian, then a cut satisfies criterion 1 of a fair division problem. b. Only Mike is a vegetarian. If the pizza is cut into such a way that one part is full vegetarian and another is full not vegetarian, then a cut doesn’t satisfy criterion 1 of a fair division problem. c. Both Tom and Mike are vegetarians. If the pizza is cut into such a way that one part is one-third vegetarian and one-six not vegetarian, the other part is one-third not vegetarian and one-six vegetarian, then a cut satisfies criterion 1 of a fair division problem. d. All statements are true.
