Afish is swimming 10.2 feet below the surface of the water. it then descends another 12.85 feet. what subtraction expression can be used to find the new position of the fish?

The subtraction expression can be used to find the new position of the fish=-10.2-12.85.

Step-by-step explanation:

Given

A fish swimming 10.2 feet below the surface of the water

fish swimming the distance in water=-10.2 feet

10.2 feet take negative because the fish swimming below the surface of the water.

Then , It descends the  another distance in water=-12.85 feet

12.85 feet take also with negtaive sign because the fish moving in  downward direction.

Now, the  expression can be used to find the new position of the fish

= -10.2 + (-12.85)

The subtraction expression can be used to find the new position of the fish

=-10.2-12.85

By using the rule when positive number is multiplied by negative number  then the answer is negative.

The new position of fish=-23.05 feet.

answer: f = 32.2m

step-by-step explanation: that is the answer

true !
