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
Real answer
3x+ -6 =63
To solve this problem and find Cassandra's younger brother's height, let's follow these steps:
Step 1: Assign a variable to represent Cassandra's younger brother's height. Let's call it "x".
Step 2: Calculate three times Cassandra's younger brother's height. This can be done by multiplying "x" by 3.
Step 3: Subtract 6 inches from the result in Step 2 to find Cassandra's height.
Step 4: Set up the equation. Knowing that Cassandra's height is 63 inches, we can write the equation as:
3x - 6 = 63
To summarize, the equation representing this problem is: 3x - 6 = 63.
Let's denote the height of Cassandra's younger brother as "x".
From the problem, we know that Cassandra's height is 6 inches less than 3 times her brother's height.
So, 3 times her brother's height is: 3x
And Cassandra's height is 6 inches less than that, which can be written as: 3x - 6
We are given that Cassandra's height is 63 inches. So, we can set up the equation:
3x - 6 = 63
Now the equation is in the form px + q = r, where p = 3, q = -6, and r = 63.
