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.
Step-by-step explanation:

(5-2)^2+(5-2)^2=

X=2
y=149
————-
Solve 8x+15=7x+17
alternate angles are equal
x=2
Substitute 2 in 8x+15 =31
180-31=149
y=149
Angles on a straight line add up to 180
Answer:
15%
Step-by-step explanation:
First problem: I believe YW: 34
ZX: 17
VX: 34. I have a pic attached but it probably doesn’t make much sense :)
