2. 17.5

3. 15.5

4. 8

Answer 1

The answer to your question is number 3. 15.5

Explanation:

Solve this problem using proportions

Equation

`(JK)/(MK) = (KL)/(KN)`

Substitution

`(10 + 4)/(4) = (7 + x + 2)/(7)`

`(14)/(4) = (9 + x)/(7)`

7(14) = 4(9 + x)

98 = 36 + 4x

4x = 98 - 36

4x = 62

x = 62 / 4

x = 15.5
