We can assume that the rim of the canyon is 0. Sarah started 3 miles below, so -3, BUT distance can never be negative, so it's considered 3 miles. Then, she went 8 miles above zero. So the 3 miles she went before reaching the rim plus the 8 miles she went after reaching the rim equals 11 miles.

So now we know that Sarah is right, but how do we know which equation is correct? Well, if we look at option C:

$|-3+8|=11$

When solving absolute value, we solve everything within the absolute value before applying the absolute value. This means that we add -3+8 first, which equals 5, and then apply absolute value, which still equals 5. This equation is not correct.

I hope this helps!

Luke has 48 books.He puts 7 books in a box.How many boxes can he fill?explain how you interpreted the remainder

Alex17521 [72]

48 books divided by 7 books per box. So since 7 can go into 48 6 times to make 42, the remainder is 6 books are left out. 6 boxes are filled. I interpreted the remainder by subtracting 42 from 48. And that's all I did. :)

I hope you like this answer and have a good night! :D
