Answer:
The sum of all the possible values for z that satisfy the above equation is -5.
Step-by-step explanation:
The given equation is
We need to find the sum of all the possible values for z that satisfy the above equation.
The given equation can be rewritten as
Cancel out common factors.
Add 2 on both sides.
Multiply both sides by -1.
Only z=-5 satisfy the given equation.
Therefore the sum of all the possible values for z that satisfy the above equation is -5.

Step-by-step explanation:
First you have to warm the block from -15° F to 32°F, the heat to needed to do this is:
After you need to melt the ice. The heat you need is:
Finally, you need to heat the water from 32° F to 200 ° F, and the heat for this is:
To have the total heat you used you have to su and
