GCF is 6
Use the distributive property by factoring out 6, like I did above
Based on the fact that the scuba diver was below sea level, the expression that shows their distance after 30 minutes is -120.9 - 42.5 and the elevation is -163.4 feet.
<h3>What is the diver's elevation?</h3>
Because the diver is below sea level, their elevation will be expressed in negatives.
This means that the elevation is -120.9 feet.
If the diver's elevation decreases by 42.5 feet, the equation for the new elevation is therefore:
= -120.9 - 42.5
When solved, this is:
= -163.4 feet
