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)
Responses
39 - c = 3.5
39 - c = 3.5
39 - 3.5 = c
39 - 3.5 = c
3.5 - c = 39
3.5 - c = 39
c - 3.5 = 39
c - 3.5 = 39
The correct equation to use to find Cassidy's height is:
c = 39 + 3.5
The equation you could use to find Cassidy's height is: 39 - 3.5 = c.
To find Cassidy's height, we can use the information given in the question. It states that Reagan is 3.5 inches shorter than Cassidy, and Reagan's height is 39 inches.
We can set up an equation to represent this relationship. Since Reagan is 3.5 inches shorter than Cassidy, we can write:
Cassidy's height - 3.5 = Reagan's height
Since Reagan's height is 39 inches, we can substitute this value into the equation:
Cassidy's height - 3.5 = 39
Simplifying this equation, we get:
Cassidy's height = 39 + 3.5
So the equation we can use to find Cassidy's height is:
39 + 3.5 = Cassidy's height
Therefore, the correct equation is:
39 + 3.5 = c
