Reagan is 3.5 inches shorter than Cassidy. If Reagan is 39 inches tall, which equation could you use to find Cassidy's height? (1 point)

Question

Responses

39 - 3.5 = c
39 - 3.5 = c

c - 3.5 = 39
c - 3.5 = 39

3.5 - c = 39
3.5 - c = 39

39 - c = 3.5

Answer 1

To find Cassidy's height based on the information given that Reagan is 3.5 inches shorter than Cassidy, we can set up the equation based on Reagan's height.

Since Reagan is 39 inches tall, and he is 3.5 inches shorter than Cassidy, we can express Cassidy's height \( c \) as:

\[ c = 39 + 3.5 \]

Rearranging it gives us:

\[ 39 - 3.5 = c \]

Thus, the correct equation to use is:

39 - 3.5 = c
