Studdy Solution
Evaluate each given option to determine which equation(s) correctly represent the relationship.
A) $7 = c \div 6$: This equation does not represent the relationship. Incorrect.
B) $c - 7 = 6$: This is the equation we derived. Correct.
C) $c \times 7 = 6$: This equation does not represent the relationship. Incorrect.
D) $6 + 7 = c$: Rearranging our equation $c - 7 = 6$ gives $c = 6 + 7$. Correct.
E) $-6 + 7 = c$: This equation does not represent the relationship. Incorrect.
The correct equations are:
B) $c - 7 = 6$
D) $6 + 7 = c$
