All u have to do is find what variable will make each statement true, I'll do one so u would get what I mean,
61. x + 13.5 < 19, this could be anything under 19 since it's supposed to be greater, I chose 5 + 13.5 < 19 which is 18.5 < 19
The number goes from 13.5 to 19 you could do it like decimals, start it from 13 then go on like this, 13,13.5,14,14.5,15,15.5,16,16.5,17,17.5,18,18.5,& 19.
Answer:
A = 4.5E2 * 3.2E6 * 3.65E2 = 4.5 * 3.2 * 3.65 * 10^10
A = 52.6 * 10^10 = 5.3 * 10^11 grams
32 divided by 4/5=32*5/4/
simplify:8*5=40
there are 40 4/5 foot pieces in 32 feet
A = pi * r^2.....r = radius and pi = 3.14
A = (3.14)(13^2)
A = 3.14(169)
A = 530.66
