Answer:
A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons.

Answer:
B. (0.88, 0.65)
Explanation:
The information that we have is that Y= -2/5x+1 and Y= 3x-2.
-2/5x+1 = 3x-2 . we have to find the value of X
1+2= 3x +2/5x
3 = 3.4x
3/3.4 = x
0.88= x
Now we replace the value of X, which is 0.88, in any of the equations to find the value of Y.
Y= -2/5 (0.88) +1
Y= 0. 65
If we replace X in the other equation, the result has to be the same.
Y= 3(0.88)-2
Y= 0.65
As a result X= 0.88 and Y= 0.65 so, the correct answer is (0.88, 0.65)
it is either physical evidence or demonstrative evidence.
