To round 2.83 centimeters to the nearest whole number, use the following:
"five or above, give it a shove. four or below, keep it low."
So, since the number is 2.83, keep the 3 low (make it a zero)
Now the number is 2.8
Since 8 is over 5, you round up.
2.83 has become the whole number 3
8-4 is4 so the answer is b

Answer:</h3>
x = -5/2
<h3>Explanation:</h3>
<u>Given</u>
(2x+1)/(x-2) + 4/x= -8/(x^2-2x)
<u>Find</u>
x
<u>Solution</u>
We note that the denominators in this equation are x and x-2. The solution set must exclude these values, as the equation is "undefined" for those values of x.
__
Multiply by x(x-2)
x(2x+1) +4(x-2) = -8
2x² +5x = 0 . . . . . . . . . . add 8, eliminate parentheses
x(2x +5) = 0
The solutions are the values of x that make these factors zero:
x = 0 . . . . must be excluded
x = -5/2
The solution to the equation is x = -5/2.
