he shoots lot of threes
It could be: 33-(3+3) = 21
3s + 1
135=3s +15 120=3s 40=s
28 3s
In its ground state, sodium (Na) has the electron configuration of 1s² 2s² 2p⁶ 3s¹. When sodium is in an excited state, one of the 3s electrons can be promoted to a higher energy level, such as 3p or 4s. For example, an excited state configuration could be 1s² 2s² 2p⁶ 3s⁰ 3p¹, indicating that the electron has moved from the 3s orbital to the 3p orbital.
It could be done by: (3*3)/(3*3) = 1
A 3s electron
3S Facility simply means sales, services and spares
To find out how many 3s go into 140, divide 140 by 3. This gives you approximately 46.67. Since we're looking for whole 3s, you can fit 46 complete 3s into 140.
-7 = 3s - 1 +1 +1 (add 1 to both sides to get the variable alone) ___ ____ -6 = 3s __ ___ (-6 and 3s both divided by 3) 3 3 -2 = s
4 3s = 4*3 = 12, which is a rational number.
The easiest way is to "flip" the inequality symbol end divide by the negative number:Example:6 < 3 - 3s6 - 3 < 3 - 3s -33 < -3s Method a) Divide by negative coefficient and flip the inequality symbol3/-3 > -3s/-3-1 > s or s< -13 < -3s Method b) Full algorithm, eliminate -3s by adding 3s on both sides3 +3s < -3s + 3s3 + 3s < 03 - 3 + 3s < 0 -33s < -33s/3 < -3/3s < -1 Looks familiar? So basically if you perform the full algorithm (method b) you can understand why we flip the inequality symbol when we have to eliminate a negative coefficient but it is faster just to flip the symbol (method a)
