500 in 2:3 is saying that there are five different parts (2 + 3)
This means that 500 needs to be split into five, which is 100.
After that all you need to do is put 2 'sections' on one side and 3 on the other.
For example, 2 : 3 = 2( x 100) : 3( x 100)
= 200 : 300
The total number of people who visitedthe ocean adventure park last year was 7,040,836
In 7,040,836, there are FOUR digits after 4.
To find value of 4, just put FOUR zeroes after 4
Thus, Value of 4 = 40000
For the second question, your first option is correct, you would rewrite 8 in power-base form 8=2^3 as the first step to solving the equation, power base form is exponential form.
1.first false because it gives 8>8, that is false , but it is written 8=8
2.false because it gives 12>8 but written -12<8
3.gives 10>8, and it is written the same true
4.gives 4>8, but written 4<8
I'm guessing that x2 is an x to the power of 2, so u can rewrite that as:
x^2 - x - 4
from there you can use completing the square, quadratic function, or factoring.
If the x2 is supposed to be 2x then it would just be as follows:
x - 4
