If 12 is 20%, then 24 is 40%, then 36 is 60%, then 48 is 80%, then 60 is 100%
So there are 60 questions on the test.
Answer: 54.4 mph
Step-by-step explanation:
First find the distance to the train station. If it took Carlos 4 hours to come back driving at 68 mph, the distance is:
= Speed * time
= 68 * 4
= 272 miles
This means that Carlos drove for 5 hours to cover 272 miles the first time. His average speed was therefore:
= Distance / time
= 272/5
= 54.4 mph
The three vertices of △ABC are in quadrant I. If △ABC is reflected in the x-axis, its image will lie in quadrant IV

Answer:
The answer would be 16b^2 - 14b + 3
Step-by-step explanation:
In order to find this, we simply need to group the terms by their variable values. We will start with the b^2 terms.
5b^2 + 24b^2 - 13b^2 = 16b^2
Now we can use all of the b terms.
-5b - 8b - b = -14b
And finally, we'll do all the constants.
4 - 1 = 3
Using all three of these together will give us the simplified form.
