will travel
STEP 1
- 12.2 +x= -4.55
STEP 2
Solve the equation using an inverse operation.
-12.2 + x= -4.55
+12.2 +12.2
7.65
Add 12.2 to both sides.
The diver will travel a vertical distance of 7.65 meters.

4. Make a Prediction Explain how you know whether the diver is
moving in a positive or a negative direction before you solve the
equation.
