Xy = 12 because if you look at the pattern the top one is 16 and the bottom one is 8 so the middle of those would be 12.
1/4 x 24 is 6.
Your welcome
Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
