Cassandra's height = 63 inches
It is given that this height is 6 inches less than 3 times her younger brother's height.
Let her younger brother's height be 'x' inches.
Thus, 3 times her brother's height would be 3x.
Since Cassandra's height is 6 inches less than this amount, we can write:
3x - 6 = 63
This is the equation in the form px + q = r that represents the problem.
So we have:
px: 3x (where p = 3)
q: -6
r: 63
Therefore, the equation representing the relationship between Cassandra's height and her younger brother's height is:
3x - 6 = 63
Cassandra measured her height as 63 inches. That is 6 inches less than 3 times her younger brother's height. How tall is her younger brother?
Write an equation in the form px + q = r to represent this problem.
