An expression is defined as a set of numbers, variables, and mathematical operations. The correct option is C.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As the given expression 4j-9=1 can be broken down into three parts, where each part is joined with the help of a comma and each part represents a mathematical operation.
Therefore,
4j → when the number j is multiplied by 4 is one operation is represented as A number times four,
-9 → minus nine, negative is the operation here,
=1 → This depicts that the result is one.
Thus, the statement that is the clearest translation of 4 j - 9 = 1 is A number time four, minus nine, is one.
Hence, the correct option is C.
