The sum of two consecutive numbers is 89. What are the two numbers?
A. 43 and 46
B. 44 and 45
C. 38 and 51
D. 45 and 46


Sagot :

  • B. 44 and 45

Explanation

  • We represent this in the form of an equation: x + (x + 1) = 89. Solving this equation we get x as 44 and the next integer (x + 1) as 45, the sum of which is 89. Similarly, knowing the consecutive integer formula finds application in a number of mathematical problems
