POQ is a straight line .The adjacent angles are three consecutive numbers. what are the measure of the angle

Solve the system of equations. y= 2x y= x^2 - 15

Solve -2(4y + 6) = 52. 5 -5 8 -8 and !

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.
