One-half of a number,<br> increased by 69 is 74.<br> What is the number?
Klio2033 [76]

Answer:

10

Step-by-step explanation:

let the number be n then half the number is \frac{1}{2} n , so

\frac{1}{2} n + 69 = 74 ( subtract 69 from both sides )

\frac{1}{2} n = 5 ( multiply both sides by 2 to clear the fraction )

n = 10

Thus the number is 10
