Simplify (1/2)4th power a. (1/16) b.(1/8) c.(1/4)

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

Will give a: 122 b: 90 c: 48 d: 180
