14/15 - 9/15 = 1/3
1/3 = 5/15
Answer:
x= -1, y=1
Step-by-step explanation:
First label the 2 equations.
7x +6y= -1 -----(1)
-x +2y= 3 -----(2)
Then choose which term you would like to eliminate. To eliminate the y term, multiply equation (2) by 3 such that the coefficient of y is 6.
(2) ×3:
-3x +6y= 9 -----(3)
Since the coefficient of y is positive 6 in both equations, subtract one equation from the other.
(3) -(1):
-3x +6y -(7x +6y)= 9 -(-1)
Expand:
-3x +6y -7x -6y= 9 +1
-10x= 10
x= 10 ÷(-10)
x= -1
Substitute x= -1 into (2):
-(-1) +2y= 3
1 +2y= 3
2y= 3 -1
2y= 2
y= 2 ÷2
y= 1
------------------------------------------------------------
2nd method: eliminating the x term
(2) ×7:
-7x +14y= 21 -----(3)
Since the coefficient of y in equation (1) is a positive 7, while that in equation (3) is a negative 7, add the 2 equations together to eliminate the x term.
(1) +(3):
7x +6y -7x +14y= -1 +21
20y= 20
y= 20 ÷20
y= 1
Substitute y= 1 into (2):
-x +2(1)= 3
-x +2= 3
-x= 3 -2
-x= 1
x= -1
Answer:
15
Step-by-step explanation:
We can find value of x using similarity ratio
(3x-5)/32 = (5x-5)/56 cross multiply expressions
56×(3x-5) = 32×(5x-5)
21x - 20x = 35 - 20
x = 15
Answer:
10√30
Step-by-step explanation:
√5*√12*√50
√12=2√3
√50=5√2
2*5√5*√3*√2
10√5*√3*√2
10√5*3*2
10√30
If Point B 
has translated 2 units to the right and 1 unit up, new coordinates of point B' are 
As per the question statement, Point B is there on a cartesian plane. Point B is translated 2 units to the right and 1 unit up.
Before solving this question, we need to know about cartesian plane system in which, there are four quadrants which are made using positive and negative axes known as positive X and negative X (same for Y axis).
Now point B lies in the first quadrant and value "3" describes the location of point on X axis and value "1" describes the location of point on Y axis.
If point B is translated 2 units to the right and 1 unit up, the locations of X and Y axes will change to value "5" on X axis and value "2" on Y axis.
Hence the coordinates of point B' are
- Cartesian Plane: The x-axis and y-axis intersect to form the two-dimensional coordinate plane known as the cartesian plane in mathematics. The origin is the point at which the x- and y-axes cross perpendicularly.
