Question

X:(4900:70)=80 x*20=240:3

Answer 1

х : 80 = 4900 : 70

х : 80 = 70

х = 80 • 70

х = 5600

х • 20 = 240 : 3

х • 20 = 80

х = 80 : 20

х = 4

Answer 2

Ответ: 5600 и 4

х:(4900:70)=80

х:70=80

(1/70)х=80 |*70

х=5600

х*20=240:3

20х=80

х=4

Answer 3

It seems like you've provided an equation or expression, but it's a bit unclear. Let me try to break down what you've written:

1. X:(4900:70)=80: This part appears to be an equation involving the variable X. However, the notation you've used (X:(4900:70)) is not standard mathematical notation, so I'm not sure what operation you're trying to perform here.

2. x*20=240:3: Similarly, this part involves the variable x and some operations, but the notation is not conventional. The right side of the equation seems to be "240:3," but I'm not sure what that represents.

If you could provide more context or clarify the notation you're using, I'd be happy to help you understand and solve the equation.
