Answer:
x = 8 is the answer
Step-by-step explanation:
In order to find the solution of Equations using Cramer's rule
we shall find matrices
D= ![\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%26-3%5C%5C1%26-2%5Cend%7Barray%7D%5Cright%5D)
=
![D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]](https://tex.z-dn.net/?f=D_%7B1%7D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-3%5C%5C-16%26-2%5Cend%7Barray%7D%5Cright%5D)
l D l = Determinant formed by coefficient of variables
Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7
l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations
Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56
here x is given by 
x = 
x = 8
Answer:
D) Scalene
Step-by-step explanation:
Easy find the least common product. In this case just take the values 1 through 5 and multiply each by 15 and 6 and the first equal product is your answer. In the end you should get 30 minutes.
Answer:
(E) 29.0
Step-by-step explanation:
If a tag is drawn at random from each box, the expected value of the sum of the tags is the sum of the expected values for each tag.
The expected value for each tag is the mean value of the numbers in its box.
The expected value of the sum of the numbers on the two selected tags is 29.
