There were 100 questions she would have answered 6 incorrectly. We now that she answered 3 incorrectly so it must have been 50 questions.
Answer:
She donated b/50 books
Step-by-step explanation:
In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:
The total number of books/ the total number of students.
The average number of books is this b/150.
Now, we are also told that Hannah donated 3 times the average number of books.
This is simply calculated by multiplying the average number of books donated by 3
This is equal to 3 * b/150 = b/50 books
Hence, Hannah donated b/650 books

Answer:
144 units
Step-by-step explanation:
3x + 8 + 4x + 10 = 8x
7x + 18 = 8x
8x - 7x = 18
x = 18
8x is length of BC
8 × 18 is length of BC
144 units
3m+4=1
subtract 4 on both sides
3m=-3
divide both sides by 3
m=-1
