So, I gotta answer this cause I gotta get atleast 20 characters in even though someone below me will answer eventually, good luck on work tho

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.
