Answer:
5,000
Step-by-step explanation:
Because 5 is in the thousands place and it is asking his neighbor 0 for help and since 0 is it a 5 or above he can't help 5 so 5 has to stay at 5,000 and can't go to 6.
I'm sorry I was late but I think this could still help you I hope have a great day:)
For the general case, the n-gon, you got

degrees. The 13-gon thus has 1980 degrees in total.
The length of a car is 4.5 meters.
The customary units - 12 inches = 1 foot
4.5 meters is about 177.165.
So, the length of a car in customary units would be 14.76375 units.....
The total angles in a polygon is 180 (n -2) where n is the number of sides.
A traingle has 3 sides. using the formula 180 x (3-2) = 180
So
X + Y + Y = 180
X + 2Y = 180 ...eq1
A pentagon has 5 sides, using the formula
180 x (5-2) = 540.
All the Y adds up to 540.
10Y = 540
Y = 54.
Use Y = 54 and sub into eq1
X + 2(54) =180
X = 180 - 2(54)
X = 180 -108
X =72
So X is 72
and Y is 54
