(13,7), (0,7) answer ?

What is the sum of these mixed numbers 2 1/8 + 4 3/8

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
