6 / t = 9 / (t+2)

9t = 6t + 12

3t = 12

t = 4   answer

The remaining length:-

6 / 4 = 11 / x

6x = 44 so x = 7.33  answer

6.  8 / w = 6 / (w - 5)

6w = 8w - 40

2w = 40 so w = 20 answer

The side marked w - 5  = 20-5 = 15 answer

8/14 = 20/x giving the top side =  35  answer

Determine graphically the​ x-value when y
Mademuasel [1]
This problem is very simple. Knowing that y=2, plug 2 into the "y" in the equation: -x+2(2)=8

-x+4=8 
subtract 4 on both sides of the equation:
-x=(8-4)
-x=4
Divide both sides of the equation by (-1):
x=(-4)
