Question

2)4:8=18:х 3)х 4 1\3=1\2:13 4) х:16=0,2:4 помогите пожалуйста очень очень важно,мне скоро уходить,умоляю!!!!!!!!!!!!!!!!!!

Answer 1

2) 4:8 = 18:х   ; 4 * х = 8 * 18  ;    х = 2 * 18   ;   х = 36
3) х : 4 1/3 = 1/2 : 13  ;    х: 13/3 = 1/2 : 13  ;   13х = 13/3 * 1/2  ;  х = 1/3 * 1/2 
   х = 1/6
4) х : 16 = 0,2 : 4  ;    4* х = 16 * 0,2  ; х = 4 * 0,2  ;   х = 0,8 

Answer 2

Вот такое решение в третьем надеюсь правильно поняла уравнение

Answer 3

Solving the Equations

Let's solve the given equations step by step.

1. 4:8 = 18:x To solve for x, we can use the concept of proportions. Cross-multiply and solve for x: \[ 4 \times x = 8 \times 18 \] \[ 4x = 144 \] \[ x = 36 \]

Therefore, the value of x is 36.

2. x + 4 + 1/3 = 1/2 : 13 + 4

First, let's simplify the right-hand side of the equation: \[ 1/2 : 13 + 4 = (1/2) / 13 + 4 = 0.038 + 4 = 4.038 \]

Now, we can solve for x: \[ x + 4 + 1/3 = 4.038 \] \[ x + 13/3 = 4.038 \] \[ x = 4.038 - 13/3 \] \[ x ≈ 0.038 \]

Therefore, the value of x is approximately 0.038.

3. x : 16 = 0.2 : 4

To solve for x, we can use the concept of proportions again. Cross-multiply and solve for x: \[ x \times 4 = 16 \times 0.2 \] \[ 4x = 3.2 \] \[ x = 0.8 \]

Therefore, the value of x is 0.8.

Conclusion

The solutions to the given equations are: 1. x = 36 2. x ≈ 0.038 3. x = 0.8
