Answer:
1)given
2)definition of congruent
3)definition of bisect
Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.
Answer:
<h2>The value of this expression is <u>
A: 3</u></h2>
Step-by-step explanation:
Let us subtract equation 1 from equation 2.
5x - 3y - 2x + 3y = 7 - 4
3x = 3
x = 1
Substituting this value of x in equation 1, we get
2x - 3y = 4
2 - 3y = 4
-3y = 2
y =
