Question

Среднее арифметическое двух чисел равно 23.Найдите второе число если первое равно 35

Answer 1

23= (35+x)/2
35+x=46
x=11 

Answer 2

To find the second number when the arithmetic mean of two numbers is 23 and the first number is 35, you can use the formula for the arithmetic mean:

Arithmetic Mean = (Sum of Numbers) / (Number of Numbers)

In this case, the sum of the two numbers is the product of their arithmetic mean (23) and the number of numbers (2).

Let's call the second number "x".

Arithmetic Mean = (35 + x) / 2

We can solve for "x":

23 = (35 + x) / 2

To isolate "x," we can multiply both sides of the equation by 2:

2 * 23 = 35 + x

46 = 35 + x

Now, to find "x," subtract 35 from both sides of the equation:

46 - 35 = x

x = 11

So, the second number is 11.
