Step-by-step explanation:
<span>7x+7x+3x+3x=2341</span><span>20x=2341</span><span>x=117.05</span>width is 3x, so<span>3(117.05)=351.15</span>Width is 351.15
Find the least common multiple of 3 and 5:
3: 3,6, 9,12,15,18,21
5: 5, 10, 15, 20
The least common multiple is 15. This means every 15 days they will be the same day.
Add 15 days to May 5:
5 + 15 = 20
The next day would be May 20
