(not really sure that is what i got)

So you need to set up something called a proportion. You should know what that is. With the ratio(fraction) 5-out-of-6, followed by an equal sign(=), and then the fraction(read carefully!) 6-out-of-n. N is your denominator. Now perform Means and Extremes, or cross multiplying. Multiply 5*n to get 5n. Multiply 6*6 to get 36. Now you need to isolate the variable from 5. Divide 5n to get 'n', and divide 36/5 to get 7.5. You end up with n=7.5. The value of n is 7.5, and that is your answer. To check, replace n with 7.5 in the proportion. Cross multiply to get the two numbers. If equivalent, then congrats, you have the right answer!

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
