We say that a set of integers is sparse if any two elements in the set differ by at least 3. Find the number of sparse subsets of $\{1, 2, 3, \dots, 12\}.$ (Note that the empty set is also sparse.)

What value of x is in the solution set of 4x – 12 s 16 + 8x?

(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

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
