Question

Сумма двух чисел равна 14,5.одно из чисел больше другого на 3,3 .найдите больше этих чисел

Answer 1

Первое число х
второе х+3,3
х+х+3,3=14,5
2х=14,5-3,3
2х=11,2
х=5,6-первое число
5,6+3,3=8,9 второе число

Answer 2

1) 3,3+x+x=14,5
     2x+3,3=14,5
     2x = -3,3+14,5 
      2x = 11,2
       x = 5,6   (1 число)
2) 14,5-5,6 = 8,9 (2 число)
   Сумма двух чисел = 8,9+5,6 = 14,5
     

Answer 3

Let's call the two numbers "x" and "y". We are given two pieces of information:

1. The sum of the two numbers is 14.5, which can be represented as an equation: x + y = 14.5

2. One of the numbers is greater than the other by 3.3: x = y + 3.3

Now, we can solve this system of equations to find the values of x and y.

Step 1: Substitute the value of x from the second equation into the first equation: (y + 3.3) + y = 14.5

Step 2: Combine like terms: 2y + 3.3 = 14.5

Step 3: Move the constant term to the other side of the equation: 2y = 14.5 - 3.3 2y = 11.2

Step 4: Isolate y by dividing both sides by 2: y = 11.2 / 2 y = 5.6

Step 5: Now that we have the value of y, we can find the value of x using the second equation: x = y + 3.3 x = 5.6 + 3.3 x = 8.9

So, the two numbers are 5.6 and 8.9, where 8.9 is greater than 5.6 by 3.3.
