Answer:
0
Step-by-step explanation:
We find the determinant of a matrix by the method below. If we have a matrix:
The determinant is
Now, using cramer's rule, we find x-value by the formula:
Where D is the determinant of the original problem and is the determinant of the x-value matrix. How do we get those?
<u><em>To get original matrix and thus D, we set up the matrix as the coefficients of x and y (s) of both the equations and to get matrix of x-value and thus , we replace the x values of the matrix with the numbers in the right hand side of the 2 equations.</em></u> We show this below:
<em />
<em>To get D:</em>
<em>To get :</em>
<em></em>
<em />
<em>Putting into the formula, we get:</em>
<em></em>
<em />
<em>Thus, the value of x is 0</em>
Answer:
The correct options are:
- cubic decimeter and liter
- cubic centimeter and milliliter
Step-by-step explanation:
1) The 1 cubic decimeter is equal to the 1 liter.
2) The 1 cubic centimeter is equal to the 1 milliliter.
3) Since,1 cubic decimeter is equal to the 1 liter.
So,
4) Since, 1 quart = 0.946353 L
5) Since,The 1 cubic centimeter is equal to the 1 milliliter.
So, 1 millimeter ≠ 1 deciliter
6) Since,1 gram = 0.035274 ounces
So, 1 gram ≠ 1ounce
1) 18
2) 4
3) 60
4) 18
5) 6
6) 4
7) 9
8) 4
9) 4
10) $35
11) 8
12) 9
13) 56
14) 10000
15) 78
16) $50
17) 10
18) 1,2,3,4,6,12
19) 1,2
20) 1000
21) 8
22) 5
23) 12
24) 366
25) 35
The answer is SSS, because have angles in both sides include side D and B
The answer is 390. Half of 12 is 6. 6 x 5 x 13 = 390! Hope I get brain lies to
