4x + 12 < 60
3x + 12 < 20
26-12 = 14
A dozen = 12 one fewer = 11 12-1 = 11
x + 12 = -12
4x + 12 < 60
To solve this problem, we first need to understand that "four times the number i" can be represented as 4i. Then, to find "12 fewer hats than 4i," we subtract 12 from 4i to get 4i - 12. Therefore, "12 fewer hats than four times the number i" is represented by the expression 4i - 12.
4n-12
Carbon - 14 has two more electrons than carbon - 12.
34,24,23,14,13, or even 12.
The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
12-
3x + 12 < 20
12 more than a number means: __+12 (a number plus 12). You can express this as an algebraic expression: n+12 or 12+n(n representing a number.)
26-12 = 14
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
The algebraic expression for "3 more than a number" can be written as x + 3, where x represents the unknown number. In this expression, the variable x is being increased by 3. This expression can be simplified further if needed, but the basic form is x + 3.
