you do 2 + 2
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
22+22
If 2s = 5 then s = 2.5. So by letting s equal 2.5 (two and one half) you will allow 2s to equal 5.
If you mean: -4+3+2s = 15 then s = 8
44 11 4 __2 2 lines go from 44 to 11 and 4 lines go from 4 to both 2s
22/2 - 2
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
22+22
two 4 1/2s and two 4*10s.
If 2s = 5 then s = 2.5. So by letting s equal 2.5 (two and one half) you will allow 2s to equal 5.
You can make the number 9 using five 2s by adding them together like this: 2 + 2 + 2 + 2 + 2 = 10, then subtracting 2: 10 - 2 = 8, then dividing by the remaining 2: 8 ÷ 2 = 4, and finally adding two more 2s: 4 + 2 + 2 = 9.
This is easy. Make two equations, and represent the sandwiches with s and the drink with d. you get: 2s+d=10 s+2d=8 After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars. (Heres the step by step algebra) 2s +dy = 10 s + 2d = 8 2s + d = 10 2s + 4d = 16 3d = 6 d = 2 2s + d = 10 2s + 2 = 10 2s = 8 s = 4 So, Sandwich = £4 Drink = £2
The element with four 2p electrons is carbon. In its electron configuration, carbon has a total of six electrons, with two occupying the 1s orbital and four in the 2s and 2p orbitals. Specifically, the configuration is 1s² 2s² 2p², indicating that there are two electrons in the 2s subshell and two in the 2p subshell.
If you mean: -4+3+2s = 15 then s = 8
The orbital notation for oxygen is 1s^2 2s^2 2p^4. This indicates that oxygen has two electrons in the 1s orbital, two electrons in the 2s orbital, and four electrons in the 2p orbital.
There is only one 2s orbital in an atom.
lithium atom is just a ball it has 1s and 2s orbitals both of which are spheres the 1s is occupied by two electrons and the 2s one electron
