Final answer:
The value of z in the equation -26z = 15 is approximately -0.577.
Step-by-step explanation:
To find the value of z in the equation -26z = 15, we need to isolate z on one side of the equation. We can do this by dividing both sides of the equation by -26, like this:
-26z/-26 = 15/-26
This simplifies to:
z = -15/26
So, the value of z is approximately -0.577.
