6, and 15 is 30
2, 9, and 15 id 54 plz mark me as brainliest
HOPE THIS HELPS!!!!!!! ;-)
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
The answer is 6 feet below the surface of the water.
Step-by-step explanation:
So the fish started out as 12m below the surface then went 3m down. If you add 12m and 3m you'll 15m, then minus with a 9m to came up with 6m. But the fish is still below surface, which gives you the answer of " 6 feet below the surface"
