Final answer:
The equation 10 + 20 = 10 x 2 is not true because 10 + 20 equals 30, whereas 10 x 2 equals 20. The correct answer is that the equation is false. Holly's assertion that the equation is true is incorrect.
Step-by-step explanation:
The question is analyzing a mathematical equation related to basic arithmetic operations. Holly suggests that the statement 10 + 20 equals 10 times 2 is true. Let's evaluate the statement given by Holly.
First, we calculate the left side of the equation, which is the sum of 10 and 20. This yields:
10 + 20 = 30
Then, we calculate the right side of the equation, which is the product of 10 and 2:
10 x 2 = 20
Comparing the two results, we can clearly see that 30 is not equal to 20. Therefore, the equation 10 + 20 = 10 x 2 is not true. Holly is incorrect in her assertion that the equation is true. The correct equation would be either 10 + 20 = 30 or 10 x 2 = 20.
