Hey there, below you will find the work and answer to your question.
2x-5=4
First lets get the 2x by itself so we have to add 5 on both sides.
2x-5=4
+5 +5
2x=9
Now we need to get the X by itself so divide each side by 2

Now we are left with the following
X=

We must simplfy the fraction
2 will go into 9 four times with 1 left over. So the mixed fraction answer would be:
x=

As a decimal you would just divide 9 and 2
x=4.5
Hope this helped!

Answer: Yes, she will finish before winter break is over.
Explanation:
Since we have given that
Number of days in winter break = 17
Number of pages she read in each day = 75
Number of pages in the Harry Potter series she wants to read = 759
Now, we'll use unitary method,
in 1 day , she read = 75 pages
in 17 days , she read is given by

and 759 pages is less than 1275 pages.
So, she will finish before winter break is over.
It would be: 39/40 * 100 = 3900/40 = 97.5%
