Answer:
The location will be at units.
Step-by-step explanation:
A scuba diver descended at a rate of units per second.
Now, if 0 represents the surface of the water and distances below the surface are negative, then after seconds the location of the diver will be given by the followings :
In one second the diver descends by 2.25 units depth.
So, in 12.5 seconds the diver will descend by units i.e.
units depth.
Therefore, the location will be at units. (Answer)
Above step we use "Multiplication property of equality"
In the above step we "Simplify on both sides of equation"
In the above step we use "Distribution property"
The above step is the result of using "Subtraction property of equality"
Above step is result of "Combining the like terms"
Above step is the result of using "Division property of equality"
Above step is result of "Simplifying fractions on either side of equation"
