Question

5целых7/18 -(x-2целых5/18)=1целая11/18

Answer 1

Ответ:

х=109\18 или х=6 целых 1\18

Пошаговое объяснение:

5целых7/18 -(x-2целых5/18)=1целая11/18

97\18-х+41\18=29\18

(97\18+41\18)-х=29\18

(97*1+41*1\18)-х=29\18

138\18-х=29\18

-х=29\18-138\18

-х=(29*1-138*1\18)

-х=-109\18

х=109\18

Проверка

97\18-х+41\18=29\18

97\18-109\18+41\18=29\18

97*1-109*1+41*1\18=29\18

29\18=29\18

В ответе можно написать х=109\18 или перевести в смешанное число и тогда х=6 целых 1\18

Answer 2

Ответ:6 целых 1/18

Пошаговое объяснение:х-2целых5/18=5целых 7/18-1целая 11/18

х-2целых 5/18=3 целых 14/18

×=3целых 14/18 + 2 целых 5/18

×=6 целых 1/18

Answer 3

To solve the equation, let's first simplify the expressions on both sides:

1. 5 целых 7/18 can be written as an improper fraction: 5 целых 7/18 = (5 * 18 + 7) / 18 = 97 / 18

2. 2 целых 5/18 can be written as an improper fraction: 2 целых 5/18 = (2 * 18 + 5) / 18 = 41 / 18

3. 1 целая 11/18 can be written as an improper fraction: 1 целая 11/18 = (1 * 18 + 11) / 18 = 29 / 18

Now, the equation becomes:

97/18 - (x - 41/18) = 29/18

To eliminate the fractions, we can multiply the entire equation by 18 to get rid of the denominators:

18 * (97/18) - 18 * (x - 41/18) = 18 * (29/18)

This simplifies to:

97 - 18(x - 41/18) = 29

Now, distribute the -18 on the left side:

97 - 18x + 41 = 29

Combine the constants:

138 - 18x = 29

Now, isolate the variable term:

-18x = 29 - 138 -18x = -109

Finally, solve for x:

x = (-109) / (-18) x = 109 / 18

Since 109 is not divisible by 18, the result cannot be written as a mixed number. Thus, the solution for x is approximately:

x ≈ 6.0556 (rounded to four decimal places)
