Suppose you are an algebra teacher grading the following solution on an examination: − 3 ( x − 6 ) = 2 − x − 3 x − 18 = 2 − x − 2 x − 18 = 2 − 2 x = − 16 x = 8 You should note that 8 checks, so the solution set is (8). The student who worked the problem therefore wants full credit. Can you find any errors in the solution? If full credit is 10 points, how many points should you give the student? Justify your position.

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow,
and purple. The spinner is spun several times, and the results are recorded below:
Spinner Results
Color Frequency
Red

Based on these results, express the probability that the next spin will land on purple as a
fraction in simplest form.
