Cassandra measured her height as 63 inches.that is 6 inches less than 3 times her brothers height.how tall is her brother
errrm anyways heres the answer for the practice
1: 1/2x + 10 = 30
2: 3x + -6 = 63
3: 1.50x + 8.00 = 12.50
4: 75 pages
5: 64 Inches
Let's say Cassandra's brother's height is x inches.
According to the information given, Cassandra's height is 63 inches, which is 6 inches less than three times her brother's height.
So, 3x - 6 = 63 inches.
Adding 6 to both sides, we get 3x = 69 inches.
Dividing both sides by 3, we get x = 23 inches.
Therefore, Cassandra's brother is 23 inches tall.
To find out how tall Cassandra's brother is, we can follow these steps:
Step 1: Let's denote the height of Cassandra's brother as "x".
Step 2: We are given that Cassandra's height is 63 inches, which is 6 inches less than 3 times her brother's height. Therefore, we can write the equation as follows:
63 = 3x - 6
Step 3: To solve for "x", we need to isolate the variable on one side of the equation. So, let's add 6 to both sides of the equation:
63 + 6 = 3x - 6 + 6
69 = 3x
Step 4: Now, divide both sides of the equation by 3 to solve for "x":
69/3 = 3x/3
23 = x
Step 5: Thus, Cassandra's brother is 23 inches tall.
To find out how tall Cassandra's brother is, we can set up an equation based on the given information.
Let's assume Cassandra's brother's height is "x" inches.
According to the information provided, Cassandra's height is 6 inches less than 3 times her brother's height.
So, 3 times Cassandra's brother's height is 3x inches.
And Cassandra's height is 6 inches less than 3 times her brother's height, which means Cassandra's height is (3x - 6) inches.
Since we know that Cassandra's height is 63 inches, we can set up the equation:
(3x - 6) = 63
To find x, we need to isolate it on one side of the equation.
First, we can simplify the equation:
3x - 6 = 63
Next, we can add 6 to both sides of the equation to eliminate the -6 term:
3x = 69
Finally, we can divide both sides of the equation by 3 to solve for x:
x = 23
Therefore, Cassandra's brother is 23 inches tall.
