We know that
<span>8 machines in the factory could make all the bottles in 5 days
so
100%-----------> 5 days
1 day------------> 100%/5------> 20% with 8 machines
1 machine work at the rate-------> 20%/8-----> 2.5% per day
day 1---------> </span><span>4 machines are used to make the bottles-----> 4*2.5%---> 10%
</span>day 2--------> 4 machines are used to make the bottles-----> 4*2.5%---> 10%
day 3-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 4-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 5-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
day 6-------->8 machines are used to make the bottles-----> 8*2.5%---> 20%
<span>total work in 6 days=[10+10+20+20+20+20]------> 100%
the answer is
6 days

<u>Answer:</u>
The expression that represents "the sum of x and 8" is x + 8
<u>Solution:</u>
Given, a sentence “the sum of x and 8”
Now, we have to write an expression that represents the above given line and check the correct option.
So, now, let us take the given expression and convert it into the polynomial form.
Take, “the sum of x and 8" → sum of x and 8 → x + 8.
Here "+" denotes sum or addition.
Hence, expression for “the sum of x and 8” is x + 8 and option c is correct.
Its b just do it backwards always works
