Question

X•9=810:3. X:8=280:4. 52:x=193-180

Answer 1

Х*9=810:3
9х=270
Х=270:9
Х=30

Х:8=280:4
Х:8=70
Х=70*8
Х=560

52:х=193-180
52:х= 13
52:13=х
Х=4

Answer 2

Let's solve each of these equations step by step:

1. X•9 = 810 ÷ 3

First, let's simplify the right side of the equation:

810 ÷ 3 = 270

Now, we have:

X•9 = 270

To isolate X, divide both sides of the equation by 9:

(X•9) ÷ 9 = 270 ÷ 9

X = 30

So, the solution to the first equation is X = 30.

2. X:8 = 280:4

First, simplify the right side of the equation:

280 ÷ 4 = 70

Now, we have:

X:8 = 70

To isolate X, multiply both sides of the equation by 8:

(X:8) × 8 = 70 × 8

X = 560

So, the solution to the second equation is X = 560.

3. 52:X = 193 - 180

First, calculate the right side of the equation:

193 - 180 = 13

Now, we have:

52:X = 13

To isolate X, multiply both sides of the equation by X:

(52:X) × X = 13 × X

52 = 13X

Now, divide both sides by 13 to solve for X:

52 ÷ 13 = 4

So, the solution to the third equation is X = 4.

To summarize:

1. X = 30
2. X = 560
3. X = 4
