Question

2) 315 - 12d=288; ьььлл​

Answer 1

-12d=288-315

-12d=-27

d=27/12

d=2.25

Answer 2

Ответ:

d= $\frac{-27}{-12}=\frac{9}{4}$ или 2,25

Объяснение:

2) 315 - 12d=288

Answer 3

To solve the equation 315 - 12d = 288, you want to isolate the variable "d." Here are the steps to do that:

1. Start with the equation: 315 - 12d = 288

2. First, you can subtract 315 from both sides of the equation to move all the terms involving "d" to one side of the equation: 315 - 12d - 315 = 288 - 315

3. This simplifies to: -12d = -27

4. Now, to solve for "d," you can divide both sides of the equation by -12: -12d / -12 = -27 / -12

5. This results in: d = 27/12

6. You can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3: d = (27/3) / (12/3)

7. Simplifying further: d = 9/4

So, the solution to the equation is: d = 9/4 or d = 2.25
