Answer:
Step-by-step explanation:
i think it is 2
Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4
8x² - 4 = 28
8x² = 28 + 4
8x² = 32
x² = 32/8
x² = 4
x = <span>±2

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"

let's firstly convert the mixed fraction to improper fraction and then take it from there, keeping in mind that the whole is "x".
