How can you just the tables to determine which girl is walking faster? how can you use the graphs?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Find the distance between the point (-3,-4), and (see the picture below)
