Ascuba diver descended at a rate of 2 1/4 per second. if 0 represents the surface of the water and distances below the surface are negative, which expression represents one way to calculate the location of the diver after 12 1/2 seconds?

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)

the solution is 12x-6y

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
