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. (2 points) x + =
The answer to this question is 3x+-6=63
Let's assume the height of Cassandra's younger brother is represented by "x".
According to the problem, we know that Cassandra's height is 6 inches less than 3 times her younger brother's height.
So, 3x - 6 = 63 is the equation that represents the problem.
Therefore, the equation in the form px + q = r is:
3x - 6 = 63.
To solve this problem, let's first represent Cassandra's younger brother's height as "x".
The problem states that Cassandra's height is 6 inches less than 3 times her brother's height. We can express this mathematically as:
Cassandra's height = 3 * brother's height - 6
Substituting Cassandra's height as 63 inches, we have:
63 = 3x - 6
Now, let's rearrange the equation to the form "px + q = r":
3x - 6 = 63
Adding 6 to both sides of the equation, we get:
3x = 69
Finally, divide both sides of the equation by 3 to solve for x:
x = 23
Therefore, Cassandra's younger brother's height is 23 inches.
The equation representing this problem in the requested form is:
3x - 6 = 63
Let's denote Cassandra's younger brother's height as "x".
We know that Cassandra's height is 6 inches less than 3 times her brother's height.
So, the equation to represent this problem would be:
3x - 6 = 63
Therefore, the equation in the form px + q = r is:
3x - 6 = 63
