Answer:
C
Step-by-step explanation:
It just says the difference between “a number” and 12. For an expression it has to have numbers grouped together
D. Five times a number is 30
Explanation:
If you write that as the real expression:
5 x f = 30 (f is a variable)
Thats not an expression, its an equation.
Equations are made up of two expressions followed by an EQUAL ( = ) sign
Expressions are combinations of variables, numbers and operation symbols (x + - /)
Basically, expressions do NOT have equal signs.
The rest of the choices can be written as an expression.
