19. C. 10,12 (D is eliminated because 15 is greater than 12, greatest common factor of the others was not 2)
20. C. 42 (The largest integer that can divide into both)
answer
45 minutes
explanation
using the equation C(m) = 0.1m + 1, C(m) is the cost of the phone call (5.50)
5.50 = 0.1m + 1 subtract 1 from both sides
4.5 = 0.1m divide both sides by 0.1
45 = m
m is the number of minutes, so 45 minutes
8/1, 16/2, 24/3, 32/4, 40/5, 48/6, 56/7, 64/8, 72/9 I’m pretty sure
