beat level 7a
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
2a+2a-7b+7b =4a
Assuming your equation = 0, then:b3+8b2+7b = 0factor out b:b(b2+8b+7) = 0factor the squared term:b(b+7)(b+1) = 0So the answers are:b = 0b+7 = 0, b=-7b+1 = 0, b=-1
7b-10 = -3
cosits 7B lol:-)
It is: 19b+7b = 26b
6c you nerds out there and the next one is 6b,6a,7c,7b,7a,8c,8b,8a and so on
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
7b-7 = 0
(-a-7b+5)4ab
5 - 7b + 6 = -24 is a linear equation in one variable. 11 - 7b = -24 Adding -11 to both sides 11 - 7b + (-11) = -24 + (-11) 11 - 7b - 11 = -24 - 11 -7b = -35 Dividing both sides by -7 -7b/(-7) = -35/(-7) b = 5
