Final answer:
Option A). The correct expression that translates 10y is '10 times y'.
Step-by-step explanation:
The correct written algebraic expression that translates 10y is A) 10 times y.
In mathematics, an algebraic expression is an expression composed of algebraic operations, variables, and constants. In algebra, the multiplication operation is represented by the multiplication symbol (×). So, when we want to express the product of 10 and y, we write it as 10 × y or simply 10y.
For example, if y represents the number of apples and we have 10 groups of apples, then the total number of apples would be 10y.
