Answer:
x = -9
Step-by-step explanation:
12 + 2x + 24 = 27 + x
(12 + 24) + 2x = 27 + x
36 + 2x = 27 + x
subtract 27 from both sides
36-27 + 2x = 27-27 + x
9 + 2x = x
subtract x from both sides
9 + x = 0
subtract 9 from both sides
x = -9
(the steps could've been faster but that shows the most work)
check:
12 + 2(-9) + 24 = 27 + (-9)
36 - 18 = 18
18 = 18
True!
so -9 is correct
The surface of the ocean is 0 meters.
Because the fish is below the surface it would be a negative number. ( it is less than 0)
The elevation of the fish would be -12 meters.
Answer:
11n=35
Step-by-step explanation:
First, you do 2n+9n
2n+9n+11n
11n-8=27
Next, you add 8 to each side
11n=27+8
11n=35
