Eating from the inside cover of the first book to the back cover of the last boook, will take the bookworm 25 full books (that is from B to Z) and for book A, the total distance should be subtracted by 1/4 (that is the length of the inside cover)
                          total distance covered = (2)(25) + (2 - 1/4)
The answer to the equation above is,
                           total distance covered = 51.75 inches

Find all numbers such that three times the number is greater than eight less than the number.
klio [65]

Answer:

ALL SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.

Step-by-step explanation:

Here, assume such number = m

Now, given :

3 times the number = 3 x ( m) = 3 m

8 less than the given number =  m - 8

Now, according to the question:

3 times the number  > 8 less than the given number

or, 3 m > m - 8

or, 3m  - m > m - 8 + m

or, 2  m > - 8

or, m > - 4

Hence, all SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.
