Question

Pls help I need help with 12

Answer 1

B. 14

Explanation:

22/x = 11/(21-x)

462 - 22x = 11x

462 = 33x

x = 14

Answer 2

Answer: The value of x is 14, answer choice B

Let y be the other line segment connected to x

Using proportions:

`(11)/(22)=(y)/(x)`

Cross multiply and simplify

`22y=11x`

`y=(1)/(2)x`

We know that x and y add to 21, so we can create the following equation:

`x+y=21`

Substitute y=(1/2)x

`x+(1)/(2)x=21`

Simplify by adding like terms

`(3)/(2)x=21`

Divide both sides by 3/2

`x=14`

Let me know if you need any clarifications, thanks!
