He can use three bookshelves. there will be 3 math books on each of the three shelves and 2 reading books on each of the shelves. 3 is the greatest common factor of 9 and 6.
2/3(x)-(-1/3(x)-4)=?
?=0
1÷3 = 0.3
2/3(x) - 0 -1/3(x) = ?
? = 0
2 ÷ 3 =.67
4(3)/ 3
your "x" becomes a negative
So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other
Your like term of this problem▶ -x + 12
2(x) - (-x) - 12 / 3
3(x) + 12
x + 4 = 0
-4 -4
---- ----
4x - 4
4x - 4 = 0
We have one solution to this equation
So, therefore your answer for this question is:
x = -4
The experiment with the least number of trials.
Experimental probability is more accurate and more close to theoretical probability by having the most trials. More trials = more accuracy. Less trials = less accuracy.
