Because it's the first number in front of three numbers. eg. 2659. Any number (in this case the number 2)in front of the three numbers (659)is always in the thousands column.
We know that both lines will be equivalent, so to solve for x we can equate the two expressions
5x = 2x + 63
We will first subtract 2x from both sides
3x = 63
We will then divide both sides by 3
x = 21
16- let x represent the number:
x+ (x+1)+(x+2)=100
collect like terms
3x+3=100
3x=97
x=~32 but we need an odd number so round to 31, since 33 would be too great
31+33+35=99
therefore, the three numbers are 31, 33, 35

271/5 = 54.2 hours
How: 2/5 +2/5+3/5 times 5 (bc its 3 different dogs with different times for 5 days) +3 (for 3 dogs) times 4/5 (bc each dog take 4/5 of an hour each) + 1/5 (for the extra 1/5 of an hour pepper wanted to stay outside)
