Answer:
x = 8
Step-by-step explanation:
The attached figure shows the angle pair representation.
Here, two lines are cut by a transversal. It means the corresponding angles are equal i.e.
37 = 6x-11
37+11 = 6x
6x = 48
x = 8
Hence, the value of x is 8.
When there are no lines, there is one region: (l, r) = (0, 1).
When there is one line, there are two regions: (l, r) = (1, 2).
When there are two lines, there are 4 regiions: (l, r) = (2, 4).
When there are 3 lines, there are 7 regions: (l, r) = (3, 7).
Each line adds a number of regions equal to its line number, so the total number of regions is one more than the sum of numbers 1 to l.
... r = (l)(l+1)/2 + 1
Answer:

Step-by-step explanation:
Answer:
x
= 5y/8
y=8x/5
Step-by-step explanation:
-3x+7y=5x+2y
7y-2y=5y
-3x+5y=5x
5x+3x=8x
5y=8x
