Cassandra measured her height as 63 inches. That is 6 inches less then3 times her younger brothers height. How tall is her younger brother?
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.
To calculate Cassandra's younger brother's height, we need to solve the equation that relates their heights. Let's assign a variable to represent the younger brother's height.
Let's call Cassandra's younger brother's height "x".
According to the given information, Cassandra's height is 63 inches, which is 6 inches less than 3 times her younger brother's height. So, we can express this as an equation:
63 = 3x - 6
To find the value of "x", we can solve this equation. Let's start by isolating "x" on one side of the equation.
Add 6 to both sides of the equation:
63 + 6 = 3x - 6 + 6
69 = 3x
Now, we want to isolate "x" by dividing both sides of the equation by 3:
69/3 = 3x/3
23 = x
Therefore, Cassandra's younger brother's height is 23 inches.
Let's start by assigning a variable to Cassandra's younger brother's height. Let's call it "x".
According to the information given, 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:
63 = 3x - 6
Now, let's solve for x:
Adding 6 to both sides of the equation, we get:
63 + 6 = 3x
Simplifying,
69 = 3x
Dividing both sides by 3, we get:
69/3 = x
x = 23
Therefore, her younger brother is 23 inches tall.
