Answer:
8.317 x 10^6 = 8,317,000
Step-by-step explanation:
You move the decimal over 6 places to the right because it's a positive number. If it were 10^-6 you would move the decimal over 6 places to the left.
Bernardo travels the same distance at 25mph as he does at 50mph. However, since 25mph is only half of 50 mph, he must travel twice as long at 25mph. If you call the time he traveled 50mph "t", then
<span>t+2t=3 </span>
<span>3t=3 </span>
<span>t=1 </span>
<span>This means he traveled 1 hour at 50mph. In this time, he traveled 50 miles. He traveled the same distance at 25mph, so his total distance was </span>
<span>50miles+50miles=100miles </span>
<span>so the round trip was 100 miles.</span>

This is equal to:

When you add a negative number, it turns into subtraction.
First, I would change it to mixed numbers:

Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:

Now, you simply subtract:
10-9=1
1/4 is your answer.
I hope this helps :)
6 x 8 = 48, the answer is 8, just divide 48 by 6.
Not sure if that is the entire question, but yes, it does. Poly comes from the Greek polus or polloi meaning much or many.
