Answer:
Step-by-step explanation:
This is your eqaution right?
4y=8x+3 , 2y=8x-3
This equation has one solution
Using the Fundamental Counting Theorem, it is found that there are 10 positive three-digit integers have the hundreds digit equal to 7 and the units (ones) digit equal to 1.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

The number of options for each selection are given as follows, considering there are 10 possible digits, and that the last two are fixed at 7 and 1, respectively:

Hence, the number of integers is given by:
N = 10 x 1 x 1 = 10.

Given :
- In a neutral atom that has an atomic mass of 22 and atomic number of 12.
To Find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> that</u><u>,</u>
- n(neutrons) + n(protons) = A
- n(neutrons) + 12 = 2 2
- n(neutrons) = 22-12
- n(neutrons) = 10
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is </u><u>1</u><u>0</u><u>.</u>
