Question

6300 : (45 + k) = 90 ​

Answer 1

Ответ:

(45 + к) = 6300 : 90 = 70

К = 70 - 45 = 25

Ответ: к = 25

Answer 2

To solve the equation for the variable "k," you need to isolate it on one side of the equation. Here's the step-by-step solution:

1. Start with the equation: 6300 / (45 + k) = 90

2. Multiply both sides of the equation by (45 + k) to eliminate the denominator: 6300 = 90 * (45 + k)

3. Now, distribute the 90 on the right side of the equation: 6300 = 90 * 45 + 90 * k

4. Simplify the right side: 6300 = 4050 + 90k

5. Next, move the constant term (4050) to the other side of the equation by subtracting it from both sides: 6300 - 4050 = 90k

6. Simplify the left side: 2250 = 90k

7. Finally, solve for k by dividing both sides by 90: k = 2250 / 90

   k = 25

So, the value of k that satisfies the equation is 25.
