Answer:
Step-by-step explanation:
3x-7=23
<=> 3x = 23 + 7
<=> 3x = 30
<=> X = 30 ÷ 3
<=> X = 10
The answer i believe would be A .because if you dived 6.98 by the 3.86 it becomes 1.8082 so on and so forth so you round and since there’s a 8 after the zero you round the zero to a one so it would be 1.81
Solutions
3 + 7 > unknown
10 > Answer
The answer to this question can be any number less than 10. Therefore the answer could be either of -8, -3, 0, 1, 2, 3, 9.
the first option is the correct one
The angular quantum number
can be any integer (whole number) between 0 and one less than the principal quantum number
.
cannot be -3, -2, or -1. The other solutions depending on what the principal quantum number is.
