Question

К*9=130+140        b:6=200-120       164-c=720:9

Answer 1

К*9= 270           b/6=80          164-c=80         
к= 270/9          b=80*6          c=164-80
к=30               b= 480           c=84

Answer 2

1)к×9=270; к=270:9; к=30; 2)в:6=80; в=80×6; в=480; 3)164-С=720:9; 164-С=80; С=164-80; С=84.

Answer 3

To solve the equations, let's go step by step:

1. K * 9 = 130 + 140

To solve for K, we need to isolate it. We'll start by simplifying the right side of the equation:

K * 9 = 270

Now, we can isolate K by dividing both sides of the equation by 9:

K = 270 / 9 K = 30

Therefore, K is equal to 30.

2. b / 6 = 200 - 120

To solve for b, we'll start by simplifying the right side of the equation:

b / 6 = 80

Now, we can isolate b by multiplying both sides of the equation by 6:

b = 80 * 6 b = 480

Therefore, b is equal to 480.

3. 164 - c = 720 / 9

To solve for c, we'll start by simplifying the right side of the equation:

164 - c = 80

Now, we can isolate c by subtracting 164 from both sides of the equation:

164 - c - 164 = 80 - 164 -c = -84

To get rid of the negative sign, we can multiply both sides of the equation by -1:

c = 84

Therefore, c is equal to 84.

In summary: K = 30 b = 480 c = 84
