Expressed algebraically, this would equal 7s - 5.
7s + 12 = 131 Therefore, 7s = 119 s = 119/7 Therefore, s = 17

The answer is 7s + 49.
The equivalent is 7s+2s = 9s
Sure thing, honey. The expression 7x7x7x7 can be written using exponents as 7^4. So, there you have it, darling. Just slap a little hat on that 7 and call it a day.
5.28751 7s equals 37.
There can be a maximum of 2 electrons in the 7s orbital, following the Pauli exclusion principle which states that each orbital can hold a maximum of 2 electrons with opposite spins.
Taking every number from 1 to 1000 inclusive, the number of digit 7s in the list totals 300.
Expressed algebraically, this would equal 7s - 5.

8 / 7 in long division is however many 7s go into 8. so there's 1x 7 in 8 with 1 remainder. For this example, assume every number beyond is a 10, multiplied by the remainder. so, it'd be 7s into 10, which is 1 again. Then 7s into 30, which is 4. Then 7s into 20, which is 2. Then 7s into 60, which 8. Then 7s into 40, which is 5. Then 7s into 50, which is 7. And this is a reoccuring number, making it 1.142857142857 and so on.
