Hey! Here are some equations. Can you determain which is true and which is false? #1. 87 + 13 = 100 #2. 217 + 14 = 230. Here is an example of an open equation! 8 * x = 224. Which value of x makes this equation true?
Sure! Let's go through the equations one by one:
#1. 87 + 13 = 100
False. The sum of 87 and 13 is 100, so this equation is false.
#2. 217 + 14 = 230
False. The sum of 217 and 14 is 231, not 230. Therefore, this equation is false.
Now, let's solve the open equation:
8 * x = 224
To find the value of x that makes the equation true, we need to divide both sides of the equation by 8:
(8 * x) / 8 = 224 / 8
Simplifying this:
x = 28
Therefore, the value of x that makes the equation true is x = 28.
