646 = 16 + 7d/11
Subtract 16 from both sides, then multiply both sides by 11/7.
In certain deep parts of oceans, the pressure of sea water, in pounds per square foot, at a depth of d feet below the surface, is given by P=16+7d/11
If a scientific team uses special equipment to measures the pressure under water and finds it to be 646 pounds per square foot, at what depth in feet is the team making their measurements?
