Question

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

Answer 1

(c-130)*50=500
с-130=500:50
с-130=10
с=10+130
с=140

x:(240:2)=15
х:120=15
х=15*120
х=1800

Answer 2

(с-130)*50=500
с-130=500:50
с-130=10
с=130+10
с=140
Ответ:140;

х:(240:2)=15
х:240:2=15
х:120=15
х=120*15
х=1800
Ответ:1800.

Answer 3

It seems like you've provided two equations:

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

Let's solve each equation:

1. (c - 130) * 50 = 500

First, let's isolate the term (c - 130) by dividing both sides by 50:

(c - 130) = 500 / 50 (c - 130) = 10

Now, add 130 to both sides to solve for c:

c = 10 + 130 c = 140

So, the value of c is 140.

2. x : (240 : 2) = 15

In this equation, it appears you're using colons to represent division. So, let's rewrite it with division symbols:

x / (240 / 2) = 15

Now, we can simplify the right side:

x / (120) = 15

To isolate x, multiply both sides by 120:

x = 15 * 120 x = 1800

So, the value of x is 1800.

To summarize:

c = 140 x = 1800
