So the class must have at least 5 more students.
1x+5=10
1x-5=10
x=5 that is the answer to the question hoped it helped.
We want to find the distance between the first page of the first book in a collection and the last page of that collection.
We will get that the distance is 13cm
Let's see how to solve this:
<u>We know that:</u>
- Each cover is 0.5cm thick
- The pages (all of them) for each volume are 5cm thick.
We want to find the distance between the first page of the first volume and the last page of the last volume.
Because we go from the first page of the first volume to the last page of the last volume, we <u>will ignore the first cover and pages of the first volume and the pages and back cover of the last volume</u>.
We ignore the pages because in normal book positioning, the first page will be on the right side of the book (and the last page is on the left side), and if we order the books from left to right, then we can ignore all the other pages of book I and book IV.
Then we have:
- one cover for volume 1.
- two covers and pages for volume 2
- two covers and pages for volume 3
- one cover for volume 4.
Now we just need to add all the correspondent measures:
( 0.5cm) + (5cm + 2*0.5cm) + (5cm + 2*0.5cm) + ( 0.5cm) = 13cm
Then the distance between the page 1 of volume I and last page of volume IV is 13cm.

Answer:
$43.04
Step-by-step explanation:
multiply the original price by .55
Answer:
Step-by-step explanation:
Club A charges $30 membership fee and charges $7 for each movie.
You can write this as :
A = 30 + 7m (where m = number of movies)
Club B charges no membership fee and it costs $12 for each movie.
B = 12m
If we want to find how many movies a member must purchase for the total cost of the two clubs to be the same, this means we are trying to solve for "m" (number of movies) when A = B.
30 + 7m = 12m
Now you can just subtract 7m from both sides.
30 = 5m
Divide both sides by 5 to find "m'.
m = 30/5 = 6
Therefore a member must purchase 6 movies
