Do this need to be simplified or factored?
Answer:
youre answer should be C
Step-by-step explanation:
hope this is helpful!
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.
The Correct Answer Would Be 4.00
Answer:
a = -2 and b = 7
Step-by-step explanation:
We need to solve for the value of "a" and "b".
We need to distribute and make the left side of the equation same form as the right side of the equation and match the coefficients, simple.
We will use the distributive property shown below to expand the left side and simplify.
<u>Distributive Property:</u> a(b-c) = ab - ac
Now, simplifying left hand side:
5x - 7(x - 1)
= 5x -7(x) -7(-1)
= 5x -7x +7
= -2x + 7
The right hand side is "ax + b".
If we match left-hand side and right-hand side, we see that:
a = -2
and
b = 7
THese are the only solution.
