Quadrilateral WXYZ is shown. Quadrilateral W X Y Z. Side W X has length 7 m + 4 n, side X Y has length 2 n minus m, side Y Z has length 9 m, and side Z W has length n minus 6. Angle W X Y has measure 5 y plus 13 degrees and opposite angle Y Z W has measure 6 y minus 8 degrees.

What must the values of m and n be for WXYZ to be a parallelogram?

m =
n =

Find all the values of x that make 0.1x + 0.25(102 - x) < 17.10 true.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
