500= 120+20x, where x is weeks
Subtract 120 from both sides
380=20x
Divide both sides by 20
19=x
19 weeks*7 days per week= 133 days
Final answer: 133 days
First you can take out a 3. And an x and a y. Thus, 3xy(3x+4y) is the answer.
Answer:
30.5x1200=36600

Find how much Neil traveled.
Since 20 minutes is a 1/3 of an hour, we need to find a 1/3 of 45 kilometers.
45/3= 15
So, Neil drove 15 kilometers.
Stephen was driving at 30 kilometers an hour.
30/2= 15
Stephen traveled for half an hour or thirty minutes.
I hope this helps!
