Средняя арифметическое чисел 7,8 и х равно 7,2.Найди у​

Answer 1

Ответ:

(7,8 + x) / 2 = 7,2

7,8 + x = 14,4

x = 14,4 - 7,8

x = 6,6

Answer 2

Sure thing! To find the value of "х" in this equation, we can use the formula for finding the average (or mean) of two numbers. The formula is: (a + b) / 2 = average In this case, we know that the average of 7.8 and "х" is equal to 7.2. So we can plug in the values we know and solve for "х": (7.8 + x) / 2 = 7.2 Multiplying both sides by 2 gives us: 7.8 + x = 14.4 Subtracting 7.8 from both sides gives us: x = 6.6 So the value of "х" that makes the equation true is 6.6.
