This is really difficult for me. if someone could me i would really appreciate it.

28 would be your answer dont mind the dots its just for the 20 character rule

Your answer would be 20, 21, 22, 24, 25, 26, 27, 28, 30. hope that helped

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
