Question

390+4900: k=460230× а+40=10000:20​

Answer 1

Ответ:

Вроде так

Пошаговое объяснение:

390+4900/K=460  

4900/K=460-390  

4900/K=70  

K=4900:70  

K=70

 

230*A+40=10000/20  

230+40=500  

230а=500-40  

230а=460  

A=460:230  

A=2

Answer 2

It seems like you've written a series of equations and expressions. Let's break them down step by step:

1. 390 + 4900:

   • The sum of 390 and 4900 is 5290.

2. k = 460230 × а:

   • It appears you want to calculate the value of "k." If "а" represents a variable, you need to provide a value for it to calculate "k." Otherwise, you have an equation but not a specific value for "k."

3. 40 = 10000 ÷ 20:

   • The division of 10000 by 20 is indeed equal to 40. This equation is correct.

If you have a specific value for "а" in the second equation, please provide it, and I can help you calculate the value of "k."
