6. A professional diver is diving at a depth of 20m. It goes up 12m, then dives 10m and then again for 7m. At what depth is the diver then? D. 28m B. 26m A. 25m C. 27m
The submarine is 52m below the surface of the water.
Step-by-step explanation:
Since we're talking about depth, we'll use negative values for every time the submarine goes down, and positive values every time it goes up. Let's set the surface of the water at 0m. We start at a depth of 30m:
-30m which then climbs 12m (+)
-30m + 12m = -18m then it dives 21m (-)
-18m - 21m = -39m then it dives 13m again (-)
-39m - 13m = -52m
To check, let's put all the values in one equation:

Answer:
The submarine is 52m below the surface of the water.
Step-by-step explanation:
Since we're talking about depth, we'll use negative values for every time the submarine goes down, and positive values every time it goes up. Let's set the surface of the water at 0m. We start at a depth of 30m:
-30m which then climbs 12m (+)
-30m + 12m = -18m then it dives 21m (-)
-18m - 21m = -39m then it dives 13m again (-)
-39m - 13m = -52m
To check, let's put all the values in one equation:
_depth
= -30m + 12m + (-21m) + (-13m)
= -30m + 12m - 21m -13m
= -30m + 12m - 34m
= -30m + (-22m)
= -30m - 22m
depth= -52m
have a good night!
