Question

420 : (y:18) - 29 = 36​

Answer 1

Ответ:

y = 116  4/13

Пошаговое объяснение:

========================

420 : (y : 18) - 29 = 36

420 : (y : 18) = 36 + 29

420 : (y : 18) = 65

y : 18 = 420 : 65

Методом пропорции

y * 65 = 420 * 18

65y = 7560

y = 7560 : 65

y = 7560/65

y = 1512/13

y = 116  4/13

Answer 2

To solve for the value of 'y' in the equation:

420 : (y:18) - 29 = 36

You can follow these steps:

Step 1: First, simplify the expression inside the parentheses by dividing y by 18.

420 : (y/18) - 29 = 36

Step 2: Divide 420 by (y/18).

(420 / (y/18)) - 29 = 36

Step 3: Simplify further by multiplying both sides of the equation by (y/18).

420 - 29 * (y/18) = 36

Step 4: Now, subtract 420 from both sides of the equation to isolate the term with 'y'.

-29 * (y/18) = 36 - 420

Step 5: Continue simplifying.

-29 * (y/18) = -384

Step 6: Divide both sides by -29 to solve for 'y'.

(y/18) = -384 / -29

(y/18) = 384/29

Now, to find 'y', multiply both sides by 18:

y = (18 * 384) / 29

y ≈ 23.72413793 (rounded to several decimal places)

So, the approximate value of 'y' is 23.72413793.
