Question

Сумма какого числа с его трехкратным значением равно 28-и?

Answer 1

Числа 7 . 3*7 + 7 = 28

Answer 2

Число ~9.33
9.33*3=27.99

Answer 3

Let's represent the number as "x". According to the information provided, the sum of the number and its three times value is equal to 28. We can express this as the equation:

x + 3x = 28

Now, combine the like terms:

4x = 28

Next, solve for "x" by dividing both sides by 4:

x = 28 / 4

x = 7

So, the number is 7, and its three times value is 3 * 7 = 21. The sum of 7 and 21 is indeed 28.
