Reagan is 3.5 inches shorter than Cassidy. If Reagan is 39 inches tall which equation could you use to find Cassidy's height?
3.5-c=39
39-3.5=c
C-3.5=39
39-c=3.5
c-3.5=39
The correct equation to find Cassidy's height can be obtained by rearranging the given information. Since Reagan is 3.5 inches shorter than Cassidy, we can subtract 3.5 inches from Cassidy's height to find Reagan's height.
Let's use the variable 'c' to represent Cassidy's height. The equation that correctly represents this relationship is:
C - 3.5 = 39
So, the answer is C - 3.5 = 39.
