Answer:
(17y/8) - 101 or (17y - 808) / 8
Step-by-step explanation:
Please enclose the fractional coefficient 1/8 inside paretheses:
(1/8)y + 17 + 2y - 118.
Now combine like terms. (1/8)y + 2y comes to (1/8)y + 16y/8 = (17/8)y.
We thus have (17/8)y + 17 - 118. Leaving (17/8)y alone, evaluate 17 - 118:
(17y/8) - 101
You could leave your answer in this form, or combine the terms using the LCD 8:
17y - 808

Answer:

Step-by-step explanation:
Given data
Number of balls= 480
we are told that 50%(half) of the balls are put back every 1
let the number of hours be x
and let the remaining ball be y after x hours
Hence the expression is given as

Here
2an-an=an
then (an-6)(an+8)
=asqnsq+8an-6an+48
=asqnsq+2an+48answer
sq is square and first We should add or subtract like terms
