Answer:
<em>3 hours</em>
Step-by-step explanation:
Given that:
Average speed of Willie = 40 km/h
After 2 hours, Gabriella traveled in opposite direction at an speed of 70 km/h.
After some time, they are 410 km apart.
To find:
Number of hours = ?
Solution:
For the first two hours, Willie traveled alone.
Formula for distance:
Distance traveled in two hours by Willie = 
Now, they both travel in opposite directions.
So the relative speed is = 40 + 70 = 110 km/h
The distance traveled by them = 410 - 80 = 330 km
Therefore, the time taken is <em>3 hours.</em>
Answer: b.not enough info
Step-by-step explanation:
Corresponding angles of congruent triangles are congruent, so 
However, we don't have all 3 interior angles of either triangle, so we cannot conclude anything.
Hey There!
In order to simplify this expression, you would have to combine the like terms.
9+1 = 10
Nothing else could be done, therefore the answer would be.
7v + 10
Hope this helped!
Answer:
360
Step-by-step explanation:
The answer is y = -8x - 20. If you were to use y = 8x - 20 then you'd get 4 = -44, which, obviously, is not true. To fix it all you need to do is add a negative sign in front of the 8. y = -8x - 20.
