The surface of the water is 0 feet. So 10 feet down means it is 0 - 10, or -10 feet as its final position.
Answer: 0
Step-by-step explanation:
We know that we use negative sign in integers to show a value is decreased or dropped and positive sign to show increase or rise.
Given : A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface.
i.e. Integer represents the distance Sabine dives down = -10 feet (1)
and Integer represents to come back to surface = +10 feet (2)
Now, the final position will be (combine (1) and (2)) :
-10+10=0
Thus, the integer represents the dive ring's final position with respect to the surface of the water = 0
Answer:
correct
x=-25
35=-2x-15
add 15 to both sides, cancels the 15 from the right
50=-2x
divide both sides by -2, isolates the x
-25=x
