Cassandra measured her height as 63 inches.That is 6 inches less than 3 times her younger brothers.how tall is her younger brother
Let h be the height of Cassandra's younger brother.
We know that 63 = 3h - 6.
Adding 6 to both sides, we get 69 = 3h.
Dividing both sides by 3, we get h = 23.
Therefore, Cassandra's younger brother is 23 inches tall.
Let's solve the problem step by step.
Step 1: Let's represent Cassandra's height with the variable "C" and her younger brother's height with the variable "B".
C = Cassandra's height
B = Cassandra's brother's height
Step 2: We are given that Cassandra's height is 63 inches, so we can write the equation:
C = 63
Step 3: We are also given that Cassandra's height is 6 inches less than 3 times her younger brother's height. We can express this relationship as an equation:
C = 3B - 6
Step 4: Since we have two different equations for C, we can find B by setting the two equations equal to each other:
63 = 3B - 6
Step 5: To solve for B, let's isolate the variable by adding 6 to both sides of the equation:
63 + 6 = 3B
69 = 3B
Step 6: Finally, divide both sides of the equation by 3 to solve for B:
B = 69 / 3
B = 23
Therefore, Cassandra's younger brother is 23 inches tall.
To find out the height of Cassandra's younger brother, we need to solve the given equation. Let's call her brother's height x.
According to the information given, Cassandra's height is 63 inches, which is 6 inches less than 3 times her younger brother's height.
We can set up an equation based on this information:
63 = 3x - 6
To solve this equation, we will isolate x (the height of Cassandra's younger brother) on one side of the equation. Here's how:
Add 6 to both sides of the equation to cancel out the -6:
63 + 6 = 3x
Simplify:
69 = 3x
Now, divide both sides of the equation by 3 to solve for x:
69/3 = 3x/3
Simplify:
23 = x
So, Cassandra's younger brother is 23 inches tall.
