Answer:
Step-by-step explanation:
<u>System Determinant</u>
The determinant of the system is the determinant of the matrix of coefficients:

<u>X Determinant</u>
This is the determinant of the matrix with the x-coefficients replaced by the constants.

<u>Y Determinant</u>
This is the determinant of the matrix with the y-coefficients replaced by the constants.

_____
This problem didn't ask, but the solution is ...
x = Dx/D = -4/-2 = 2
y = Dy/D = -2/-2 = 1
(x, y) = (2, 1)
B 400 will be your answer to 348
Answer:
D=3+4h becausw they are counting by 3 starting from four
Given:
The number of red flowers =24
The number of white flowers = 18
As flowers divided equally.

The HCF ( highest common factor) of 24 and 18 is 6.
The largest number of group that can be created is 6.
This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.
