Question

if GH=7z-1 and BC=4z-3 what is GH​

Answer 1

Answer:

-17/3

-5.666667

Step-by-step explanation:

Assuming GH≅BC

You can write this equation to represent the problem:

$7z-1=4z-3$

Then, just solve for z:

$7z=4z-3+1\\7z-4z=-2\\3z=-2\\z=-\frac{2}{3}$

Now, plug that back into GH:

$7(-\frac{2}{3})-1\\\\-\frac{14}{3}=1\\\\-\frac{17}{3}$

Thats -17/3, or -5.666667
