Question

Cassandra measured her height at 63 inches that is 6 inches less than three times her younger brothers height how tall is her younger brother write an equation in the form PX plus Q equals R to represent this problem the box says blank X plus blank equals blank. What's the answer?

Answer 1

Let's represent Cassandra's younger brother's height by the variable X.

According to the problem, Cassandra's height is 6 inches less than three times her younger brother's height.

This can be represented by the equation: 3X - 6 = 63

To write it in the form of PX + Q = R, we need to rearrange the equation:
3X - 6 = 63
=> 3X = 63 + 6
=> 3X = 69
=> PX = 3X (P = 3)
Q = -6
R = 69

So, the equation in the form PX + Q = R is: 3X - 6 = 69
