Understand the Problem
The question is asking us to determine what number, when multiplied by 10, results in 30. To solve this, we can set up the equation 10x = 30 and solve for x.
Answer
The solution is \( x = 3 \).
Answer for screen readers
The final answer is ( x = 3 ).
Steps to Solve
- Set up the equation
We start with the equation derived from the problem statement, which is:
$$ 10x = 30 $$
This equation indicates that 10 times some number ( x ) equals 30.
- Isolate the variable
To find ( x ), we need to isolate it. We can do this by dividing both sides of the equation by 10:
$$ x = \frac{30}{10} $$
- Calculate the value
Now, we can perform the division to find the value of ( x ):
$$ x = 3 $$
The final answer is ( x = 3 ).
More Information
This means that if you multiply 3 by 10, you will indeed get 30. This type of problem is a straightforward example of solving a linear equation.
Tips
- Incorrect division: A common mistake is miscalculating the division step. Make sure to divide carefully to avoid errors in finding the value of ( x ).
