Cassandra measured her height as 63 inches.that is 6 inches less than 3 times her brothers height.how tall is her brother

Answer 1

Let's say Cassandra's brother's height is x inches.
According to the information given, Cassandra's height is 63 inches, which is 6 inches less than three times her brother's height.
So, 3x - 6 = 63 inches.
Adding 6 to both sides, we get 3x = 69 inches.
Dividing both sides by 3, we get x = 23 inches.
Therefore, Cassandra's brother is 23 inches tall.
