Step-by-step explanation:
Well, let's walk through it, shall we?
3x − 5 = 4 + 3x
Our first step is to simplify both sides of the equation.
3x − 5 = 4 + 3x
3x + −5 = 4 + 3x
3x − 5 = 3x + 4
Then, we subtract 3x from both sides.
3x − 5 − 3x = 3x + 4 − 3x
−5 = 4
FInally, we'll add 5 to both sides.
−5 + 5 = 4 + 5
0 = 9
In conclusion, your answer is:
This would be false. x = -3 is not a solution to 3x - 5 = 4 + 3x
64 + 0 + 0 + 8 + 0 + 0 + 1 = 73. So, 73 is the decimal equivalent of the binary number 1001001.
Answer:
113.1 (113.0973355...)
Step-by-step explanation:
1. Use the sphere volume formula of π.
2. Divide 6 by 2 in order to get a radius of 3.
3. Substitute 3 in for r.
4. Cube the 3, you'll get 27.
5. Multiply 27 by Pi and 4/3.
6. You get 113.1 as a rough estimate, or 113.0973355... for a more exact number. If you leave it in Pi terms, it's 36π.
