I think a professor who was a plant biologist in Utah wanted to learn where animals eat or drink and if that location changes. Scientists discovered differences in the isotopes of hydrogen and oxygen in hair and in the water in various location in the US. He then hypothesized that this could apply to humans too.

If x =2/3, what is the value of the following expression? X^3 x 3 divided by 2/9 + 9x - 7-6x
Damm [24]
This is a basic algebraic equation

And will be using PEMDAS to solve

P: Parentheses
E: exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction

If you are unaware of PEMDAS this is the order at which you solve algebraic equation. So start from “P” and end with “S”


X= 2/3

2/3^3 Times 3 Divided by 2/9 + 9(2/3) - 7 - 6(2/3)

Now, personal I’d choose to convert fractions to decimals to simplify solving the equation. I doubt this is the only way to solve for the equation but I find this is the easiest

To convert a fraction to decimal you divide the numerator by the denominator.

So 2/3 is 0.666667
And
That means 2/9 is 0.222222

0.666667^3*3/0.222222+9(0.666667)-7-6(0.666667)

Making you answer roughly -0.999989

Hope this helps, but I’m not sure if this is completely right or not

Answer:

We first have to find the volume of the cube: (0.3 * 0.3 * 0.3) we then get 0.027, then we plug in the numbers for the density formula. D = 18.954/0.027 will give us 702.
