30*(1 5/6 х +3 1/5)=231​

Answer 1

Ответ:

Пошаговое объяснение:

30 * (1 5/6 х + 3 1/5) = 231

1 5/6х + 3 1/5 = 231 : 30

1 5/6х + 3 1/5 = 7,7

1 5/6х = 7,7 - 3 1/5

1 5/6х = 7,7 - 3,2

1 5/6х = 4,5

х = 4,5 - 1 5/6

х = 4 5/10 - 1 5/6

х = 4 1/2 - 1 5/6

х = 4 3/6 - 1 5/6

х = 3 9/6 - 1 5/6

х = 2 4/6

х = 2 2/3

Answer 2

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

Given equation: 30*(1 5/6 x + 3 1/5) = 231

Step 1: Convert the mixed numbers to improper fractions. 1 5/6 = (61 + 5)/6 = 11/6 3 1/5 = (53 + 1)/5 = 16/5

Step 2: Substitute the fractions back into the equation. 30 * (11/6 x + 16/5) = 231

Step 3: Distribute the multiplication on the left side of the equation. (30 * 11/6)x + (30 * 16/5) = 231

Step 4: Simplify the fractions on the left side. (165/6)x + (480/5) = 231 (55/2)x + 96 = 231

Step 5: Subtract 96 from both sides. (55/2)x = 135

Step 6: Multiply both sides by 2/55 to solve for x. x = (135 * 2) / 55 x = 270 / 55 x = 54 / 11

So, the solution to the equation is: x = 54 / 11 or approximately 4.9091.
