The sum of 2 consecutive odd integers is 92. Find the numbers.
padilas [110]

Answer:

  45, 47

Step-by-step explanation:

Their average, 92/2 = 46, is the even integer between them. The two integers of interest are 45 and 47.

___

Any consecutive integers of the same parity (odd or even) differ by 2. If x is the smaller, then x+2 is the larger.

We suppose you're supposed to write the equation ...

  x + (x+2) = 92

  2x = 90 . . . . . . subtract 2

  x = 45 . . . . . . . .the smaller integer is 45; the larger one is x+2 = 47.

Paha777 [63]
1. If x=6, 6+37=?46 43≠46. It isn’t a solution.
2. If x=12, 12+37=?46 49≠46. it’s not a solution.
3. If x=9, 9+37=?46. 46=46. It’s a solution!
4. If x=83, 83+37=?46. 120≠46. Not a solution.

Only x=9 Is a solution.
