Answer:
t=-6
Step-by-step explanation:
12/2=6
t-6=3t/2-3
t-3t/2=-3+6
2t/2-3t/2=3
-t/2=3
-t=3*2
-t=6
t=-6
First set the equation equal to 0 by subtracting n from both sides.
That leaves us with 8n² - 11n = 0.
Since the GCF on the left is n, we can
factor it out to get n(8n - 11) = 0.
So either n = 0 or 8n - 11 = 0.
Solving for n in the second equation, we get n = 11/8.
So our solution is {0, 11/8}.
The mean of the data set A is 4.58 while the mean of data set B is 5.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The mean of a set of numbers is the average of that group of number. It is the ratio of the sum of the data to the total number of data.
Mean of data set A = [(3 * 1) + (4 * 3) + (5 * 2) + (6 * 2) + (7 * 3) + (8 * 1)] / (1 + 3 + 2 + 2 + 3 + 1) = 4.58
Mean of data set B = [(4 * 2) + (5 * 2) + (6 * 2)] / ( 2 + 2 + 2) = 5
The mean of the data set A is 4.58 while the mean of data set B is 5.

Answer:
5 -2√10 = C
Step-by-step explanation:
√25 -√40
√25 = √5 x5 = √5² = 5
√40 = √5 x 8 = √5x 2x4 = √10x4 = √10x 2² = 2√10 (when the 2 comes back into the square root it become 2²)
√25 -√40 = 5 -2√10
