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
Let x be the height of Cassandra's younger brother.
The equation representing this problem is 3x - 6 = 63.
Let's say Cassandra's younger brother's height is represented by "x".
According to the problem, Cassandra measured her height as 63 inches, which is 6 inches less than 3 times her younger brother's height.
So we can write the equation as:
3x - 6 = 63
This equation represents the relationship between Cassandra's height (63 inches) and her younger brother's height (x).
To find her younger brother's height, we need to set up an equation.
Let x represent her younger brother's height.
According to the problem, Cassandra's height is 6 inches less than 3 times her younger brother's height. So, we can write the equation as:
3x - 6 = 63
In this equation, 3x represents 3 times her brother's height, and (3x - 6) represents Cassandra's height. We subtract 6 from 3x because Cassandra's height is 6 inches less than 3 times her brother's height.
Now you can solve this equation to find the value of x, which represents her younger brother's height.
The 6 was wrong
Apologies for the confusion. Let's correct the equation:
Cassandra measured her height as 63 inches, which is 6 inches less than 3 times her younger brother's height. Let x represent her younger brother's height.
The correct equation is:
3x - 6 = 63
In this equation, 3x represents 3 times her brother's height, and (3x - 6) represents Cassandra's height. We subtract 6 from 3x because Cassandra's height is 6 inches less than 3 times her brother's height.
