Answer: <em>a + ( 2a - 7 ) = 41</em>
Explanation:
Let be "a" the Nicci's age and "s" the Nicci's sister.
You know that the sum of Nicci's age and her sister's age is 41. This can be represented with the following equation:
<em>a + 8 = 41</em>
And knowing that Nicci's sister is 7 years less than twice Nicci's age, you can write another equation to represent this:
<em>8 = 2a - 7</em>
Now, substitute the second equation into the first equation in order to find the equation that represents this relationship.
Then, this is:
<em>a + ( 2a - 7 ) = 41</em>

Answer:
very specific...sus...yea no one knows
Step-by-step explanation:
In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .
The answer would be 0.208.....
