1) cindy and mary are running in a marathon. cindy ran 21.6 miles and has 4.6 miles left to run. mary ran 24 miles. how many more miles does mary have left to run?

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.
