Answer:
Collen's average speed was 11.875 miles/h
Step-by-step explanation:
The average speed is given by the total distance travelled divided by the time at which the route was completed. So in this case the total distance is 9.5 miles and the time to complete it was 0.8 hour. We then have:
average speed = total distance/ time
average speed = 9.5/0.8 = 11.875 miles/h
Collen's average speed was 11.875 miles/h
Answer:

Step-by-step explanation:
To factor this, you must first take out the GCF (Greatest Common Factor), that
and -147 both have. The terms only have 3 in common, which can be divided with

However, we're still not done since 49 is a perfect square and
can be split into 2, like so:

If you're unsure about the final answer, you can multiply it all together to see if you got the original expression.
ANSWER :
It will be false , it is not the multiple of 10
The answer is 97, because when you add up 42 and 55 you get 97. Then you subtract that by 180 because a triangles angles add up to 180. 180-97=83. Z=83. Z and y are supplementary to eachother, so therefore 180-83= 97. Supplementary means they add up to 180.
