Answer:
Step-by-step explanation:
First you should subtract 14-3 which you get 11
Estimate : 14 - 2 = 12......20 - 12 = 8
real thing :
13.59 - 1.85 = 11.74
20 - 11.74 = 8.26
63-x=62
Then subtract 62 and 63
-x=-1
x=1
Lt1 = 45; Lt2 = 120; Lt3 = 75
:
Prime factor each:
45: 3,3,5,
120: 2,2,2,3,5
75: 3,5,5
:
Lcm of all three: 2,2,2,3,3,5,5 Multiply this: 1800 secs they will all Flash
:
1800/60 = 30 min: At 9:05Pm this should occur
