Answer:
Every night
Step-by-step explanation:
The problem statement tells you ...
"Every night Chris reads a number of pages that can be rounded to the nearest hundred."
Then it asks you ...
"On what nights does Chris read a number of pages that can be rounded to the nearest hundred?"
If we take the problem statement at face value, the answer must be ...
"Every night."
So we know that it must be between 9.5 9.7.. So it has to be 9.56763865854637984... (rounded 9.57) it is irrational because it has no pattern.
2x-y=3
use the substitution method
2(2)-y= 3
4-y= 3
move 4 to the other side
sign changes from +4 to -4
4-4-y= 3-4
-y= 3-4
-y=-1
mutiply both sides by -1 to get +y
(-1)(-y)= (-1)(-1)
y= (-1)(-1)
Answer: y= 1
