Question

translate this sentence into an equation.
the difference of chaus age and 9 is 47
use the variable c to represent chaus age.

Explanation:

Step1: Identify the operation from "difference"

The word "difference" means subtraction. So we need to subtract 9 from Chau's age (represented by \( c \)) or subtract Chau's age from 9? Wait, the sentence is "the difference of Chau's age and 9", usually "difference of A and B" is \( A - B \). So Chau's age is \( c \), so it's \( c - 9 \).

Step2: Set equal to 47

The problem says this difference is 47, so we set \( c - 9 \) equal to 47. So the equation is \( c - 9 = 47 \).

Answer:

\( c - 9 = 47 \)
