Answer:
20
23 is between 20 and 30, but it's closer to 20. So 23 is rounded down to 20.
Answer:
When someone says two points are collinear he means to say that two points are lying on the same line
Suppose a line and take two points A and B on it.
A and B are said to be collinear because they are lying on the same line
Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11
----------------
5x = 36
x = 36/5
