Answer:
Total eclipse was 
minutes longer than in 2005.
Step-by-step explanation:
It is given in the question that total eclipse in 2003 lasted 
minutes and in 2005 it lasted 3/8 of a minute.
We have to calculate how much longer did it last in 2003.
So we have to subtract the duration in 2003 by duration in 2005
Total time taken in 2003- total time taken in 2005
minutes

Valid
Step-by-step explanation:
3(x-4)=x+4 <em>Given</em>
3x-12=x+4 <em>Distribute</em>
2x=16<em> Subtract x from both sides and add 12 to both sides</em>
x=8 <em>Divide each side by 2.</em>

1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47
So 16 integers.
Based on the given nomenclature of angles, I think the illustration would look like that shown in the attached picture. The common vertex is point B, that's why the middle point of the given angles is B. Now, according to Angle Addition Postulate, the individual interior angles should sum up to the total angle. So, the equation would be
m∠ABD = m∠ABC + m∠CBD
m∠ABC = m∠ABD - m∠CBD
m∠ABC = 85° - m∠CBD
