In this big ol' word problem, this is just an instance of basic multiplication/division.
If it takes it 1 hour for 3 meters...
12 ÷ 3 = 4.
It would take 4 hours for the water level to change to 12 meters.
Answer:
2x + 3 - 4/x
Step-by-step explanation:
6x^2 + 9x - 12/ 3x

2. Divide each term in the numerator by the denominator.
2x^2/x + 3x/x - 4/x
3. Simplify each term. Then when you finish to simplify your answwer would be: 2x + 3 - 4/x

Answer:
145 degrees .....................
Answer: E. 40
Step-by-step explanation:
<u>Concept: </u>
- When you encounter questions that state "what percent of [a] is [b]" then it means asking for a fraction of b to a, which is "(b/a)×100%".
- If you are still confused, I would provide some examples
- What percent of 20 is 5: (5/20)×100% = 25%
- What percent of 10 is 2: (2/10)×100% = 20%
---------------------------------------------------------------------------
<u>Solve:</u>
(16/40)×100% = 0.4 × 100% = 40%
Hope this helps!! :)
