Question

Your friend has read 6 more than twice as many pages as your

sister has read. Let 4
be the number of pages that your sister has
read. Write an expression for the number of pages that your friend
has read

Answer 1

Expression: 2s + 6

# of Pages Friend Read: 14 pages

Explanation:

Let's call the number of pages your sister has read, s, and the number of pages your friend has read, f. We will make our equation first. If your friend has read 6 more than twice as many pages as your sister has, your equation would look like this:

f = 2s + 6

That is your equation for how many pages your friend read, your expression would be just 2s + 6. Now, we will substitute in 4 for s, and we get:

f = 2 * 4 + 6

Multiplying gives:

f = 8 + 6 = 14

So your friend has read 14 pages.

Hope this helped!
