first of all we need to know our place values.
4= hundreds
5= tens
5= units/ones
2= tenths
1= hundredths
8= thousandths
7= ten thousandths.
To round a number to the nearest thousandth, look at the next place value to the right (the ten thousandths). If it's 4, or less, just remove all the digits to the right. If it is 5 or greater, add 1 to the digit in the thousandths place and then remove all the digits to the right.
Now to your question; the ten thousandths digit is greater than 5 (7). So we would add 1 to the digit in the thousandths place ( which is 8) then remove all digits to the right.
So our result end up in :

Answer:
and
Step-by-step explanation:
To solve this, you must set up a system of equations. The first sentence says that there are two numbers and that their sum is 91, so your first equation is . For the next equation, it says that the difference of those same numbers is 1, which means that the equation is . Now, putting those two together for the system of equations, it's easiest to add them. The result will be which when simplified gives you the value of x. Taking the value of x, you can substitute in the second equation to find the value of y.
Hope this helped!
An independent system has different slopes hence has a unique solution.
If two lines have the same slope then, they are inconsistent. The reason is that the two lines could have NO SOLUTION or INFINITELY MANY SOLUTION.
An inconsistent system that have infinitely many solution is said to be dependent.
Now let us make the subject in both equations, to obtain,
For the seccond equation, we have
Wow, the two systems have the same slope and intercept. This means the system has infinitely many solution, hence it is dependent.
<h2>
The two systems are dependent</h2>

Mean is the average in numbers by the way!
Anyways, the answer is about 14.3
or...
14 1/3
Step-by-step explanation:
14 + 12 + 17 = 43
43 ÷ 3 = 14.333333...
