Question

2) (18 - x) + 7 1/12 = 12 5/12​

Answer 1

Ответ:

12 2/3

Пошаговое объяснение:

2) (18 - х) + 7 1/12 = 12 5/12

18 - х = 12 5/12 - 7 1/12

18 - х = 5 4/12 = 5 1/3

х = 18 - 5 1/3

х = 12 2/3

Answer 2

Пошаговое объяснение:

(18 - х) + 7 1/12 = 12 5/12

18 - х = 12 5/12 - 7 1/12

18 - х = 5 4/12

18 - х = 5 1/3

х = 18 - 5 1/3

х = 17 3/3 - 5 1/3

х = 12 2/3

Answer 3

To solve the equation (18 - x) + 7 1/12 = 12 5/12, we need to simplify the equation and isolate the variable x.

First, let's convert the mixed numbers to improper fractions: 7 1/12 = (12 * 7 + 1) / 12 = 85 / 12 12 5/12 = (12 * 12 + 5) / 12 = 149 / 12

Now we can rewrite the equation as: (18 - x) + 85/12 = 149/12

To remove the fractions, we can multiply both sides of the equation by the common denominator of 12: 12 * (18 - x) + 12 * (85/12) = 12 * (149/12)

Simplifying, we have: 216 - 12x + 85 = 149

Combine like terms: 301 - 12x = 149

Next, isolate the variable x by subtracting 301 from both sides: 301 - 301 - 12x = 149 - 301 -12x = -152

Finally, solve for x by dividing both sides by -12: x = (-152) / (-12) x = 12.67

Therefore, the solution to the equation (18 - x) + 7 1/12 = 12 5/12 is x = 12.67.
