Answer:

36 pages /4 hours.

Step-by-step explanation:

In order to find how many pages aaila reads in one hour, we need to take the amount she read in 4 hours and divide it by 4.

This is because that will allow us to find, the amount she reads in one hour.

She read 36 pages in 4 hours.

Therefore, our expression is 36 pages /4 hours.

Sarah started 3 miles below the rim of the canyon and hiked until she was 8 miles above the rim. Her brother Sam said she hiked
larisa86 [58]

Answer:

D

Step-by-step explanation:

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