18. use the spinner to find each theoretical probability

a. p (an even number)
b. p (a number greater than 3)
c. p (an odd number)

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.
