Question

If GH=7z-1 and BC=4z-3 what is GH​

Answer 1

-17/3

-5.666667

Explanation:

Assuming GH≅BC

You can write this equation to represent the problem:

`7z-1=4z-3`

Then, just solve for z:

`7z=4z-3+1\\7z-4z=-2\\3z=-2\\z=-(2)/(3)`

Now, plug that back into GH:

`7(-(2)/(3))-1\\\\-(14)/(3)=1\\\\-(17)/(3)`

Thats -17/3, or -5.666667
