In the expression (8 + 2t), the variable is (t). A variable is a symbol used to represent an unknown quantity, and in this case, (t) can take on different values. The expression combines a constant term (8) and a term that includes the variable multiplied by a coefficient (2).
It is n
8
The variable expression of "z plus 8" is represented as z + 8. In algebra, variables like z can take on different values, while constants like 8 remain the same. When you see "z + 8" in an equation or expression, it means that the variable z is being added to the constant 8.
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
In the expression 5 + y + 8, y is a variable. We know how much 5 and 8 are, those are definite quantities. Only y has an unknown, and hence variable value.
