Answer: 9
Step-by-step explanation:
Let the consecutive odd numbers be y, y+2 and y+4.
Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:
5y = 2(y+4) + 7
5y = 2y + 8 + 7
5y = 2y + 15
5y - 2y = 15
y = 3
The smallest odd number is 5
The largest integer will be:
= y + 4
= 5+4
= 9

First, determine how many half lives have expired by dividing the time by the half-life. So:
55/20 = 2.75
That means that only 2^(-2.75) = 0.148650889 = 14.8650889% of the original substance remains. So just divide the amount remaining by 0.148650889 to get the original amount.
9 / 0.148650889 = 60.5445419
So originally, there was 60.5 milligrams per square centimeter 55 years ago.</span>
If angle 3 is adjacent (right next to) angle 5, then its measure would be 60 degrees. If angle 3 is congruent (vertical or alternate interior/exterior) to 5, it is 120.
