Solve for r. k=ar/p a r=ka/p b r=kap c r=kp/a d r=a/kp

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

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.

How many heads would you expect if you flipped a coin twice? first, fill in the table below with the correct probabilities. hint: the sample space for flipping a coin twice is {hh, ht, th, tt}. a = b = c = f
