Answer:
127.75
Step-by-step explanation:
In this geometric series, it is clear that every number is half of the previous number. From that, we can continue on the series as shown below...
64+32+16+8+4+2+1+0.5+0.25
The series above is 9 total terms. We can add those together to get our answer.
64+32+16+8+4+2+1+0.5+0.25 = 127.75
B:15 Students
This is because 41 students (French) + 22 students (German) = 63 students
Of those 63, 9 are taking both French and German but they are already included in the counts of 41 and 22.
Since we know the languages of 63, we subtract 63 from 78 to find those who are taking neither.
78-63=15
The answer is 8-36 when n=12
Answer:

Step-by-step explanation:

(Subtract 2x from both sides of the equation)
(Divide both sides of the equation by 2 to get rid of y's coefficient)
(Simplify RHS)
