Question

(54-x):3,5=17:35:1,02

Answer 1

(54 - х) : 3,5 = 17 : 35 : 1,02

(54 - х) : 3,5 = 17/35 : 1,02 - это пропорция

(54 - х) * 1,02 = 3,5 * 17/35 - свойство пропорции

55,08 - 1,02х = 1,7

1,02х = 55,08 - 1,7

1,02х = 53,38

х = 53,38 : 1,02

х = 5338/102

х = 157/3 - сократили на 34

х = 52 целых 1/3

Answer 2

To solve the equation, we need to find the value of the variable "x." Let's break down the equation step by step:

(54 - x) / 3.5 = 17 / 35 / 1.02

First, we simplify the right side:

17 / 35 / 1.02 = 17 / (35 * 1.02) = 17 / 35.7

Now, the equation becomes:

(54 - x) / 3.5 = 17 / 35.7

To isolate "x," we'll multiply both sides by 3.5:

(54 - x) = (17 / 35.7) * 3.5

Now, we can calculate the right side:

(17 / 35.7) * 3.5 ≈ 1.66868940754

Now, we can rewrite the equation:

54 - x ≈ 1.66868940754

To solve for "x," we subtract 1.66868940754 from both sides:

x ≈ 54 - 1.66868940754

x ≈ 52.33131059246

So, the approximate value of "x" is 52.3313 (rounded to four decimal places).
