Answer: 363.6 miles.
Step-by-step explanation:
1. You know that the motorist traveled 250 miles on 11 gallons of gas. Then, to calculate how far could the motorist go on 16 gallons of gas (with the same vehicle), you only need to multiply 16 gallons by 250 miles and divide this by 11 gallons.
2. Keeping this on mind, let's call the distance the motorist could go on 16 gallons of gas
, then:

3. Therefore, you obtain the following result:

Simply solve the square.
(X^2-6)^2
She did not divide 28 by7
To find the average number of enrollments per day, what you would want to do is add all of the numbers and then divide it by how many numbers there are.
Your Equation would look like this:
17+19+23+14+25+28 = ?
When you solve it. you would get:
126
126 would be the total amount of enrollments, but the question is asking you to find the average enrollments PER day. In this case, you would divide your total enrollments by how many numbers there are in the question. There are 6 numbers in the question, or six days, that being 17, 19, 23, 14, 25, and 28. So you would get your total amount of enrollments and divide it by 6
Your equation would look like this now:
126÷6=21
The average number of enrollments per day is 21.
If my math is right it should be b
