Question

Si el promedio aritmético de 25; 31 y x es 37,
¿cuál es el valor de x?

Answer 1

The value of x is 55.

Step-by-step explanation:

To find the value of x, we need to calculate the sum of the numbers and then divide it by the total count of numbers. The given numbers are 25, 31, and x, and their average is 37. So, we can set up the equation as:

(25 + 31 + x) / 3 = 37

Now, we can solve this equation:

25 + 31 + x = 3 * 37

56 + x = 111

x = 111 - 56

x = 55

Therefore, the value of x is 55.
