The expression that represents the cost of y books is 12y + 3.

Given that,

  • The charge for the first copy of the book is $15.
  • For each extra copy, the charge is $12.
  • Here we assume the number of books be y.

Now based on the above information, the expression should be

= 12y  + (15 - 12)

= 12y + 3

Therefore we can conclude that option F is correct.

A plumber had a pipe that was 2 yards long he cut 18 inches off the end of the pipe
balandron [24]
To convert yards to feet, you would multiply it by 3. So, since there the pipe is 2 yards long, you could multiply 2*3 to get 6 feet. Then you can convert feet to inches by multiplying it by 12. 6*12 is equal to 72, so 2 yards is equal to 72 inches. Lastly, you can subtract 18 from 72, to get 54, and 54 inches would be your final answer.
