Question

Уровнения  (c-130)*50=500: x : (240:2)=15

Answer 1

(с-130)*50=500

с-130=500:50

с-130=10

с=10+130

с=140

 

х:(240:2)=15

х:120=15

х=15*120

х=1800

Answer 2

Let's first simplify the equation on the left side of the equal sign:

(c-130)*50 = 500

We can divide both sides by 50 to isolate the expression in parentheses:

c - 130 = 10

Adding 130 to both sides gives us:

c = 140

So c equals 140.

Now let's simplify the equation on the right side of the equal sign:

240:2 = 120

So x divided by 120 equals 15. We can multiply both sides by 120 to solve for x:

x = 15 * 120

x = 1800

Therefore, the solution to the equations (c-130)*50=500: x : (240:2)=15 is c = 140 and x = 1800.
