Cassandra measured her height as 63 inches. That is 6 inches less then3 times her younger brothers height. How tall is her younger brother?

Answer 1

Let's assume Cassandra's younger brother's height is x inches.

According to the given information, Cassandra's height is 6 inches less than 3 times her younger brother's height.

Therefore, 63 = 3x - 6

Adding 6 to both sides, we get 63 + 6 = 3x

69 = 3x

Dividing both sides by 3, we get x = 23

Therefore, her younger brother is 23 inches tall.
