Ok, i've got most of it done. But i'm stumped as of right now.

Question:
1(0? idk..) ft ? in. = 30 in.

Seriously stumped.

Got me stumped too, since I don't know what you are talking about.

Not familiar with a unit called idk

To solve this problem, you need to convert 1(0?) feet into inches and then compare it to the given measurement of 30 inches. Let's break it down step by step:

1. Firstly, let's deal with the "(0?)" part. It seems like there is some uncertainty regarding the number before the parentheses. To determine the number of feet, we need to clarify the value in the parentheses. Is there any additional information or context for what the number could be?

2. If there is no additional information, we can assume that the number before the parentheses is 1. So, we have 1(0?) feet.

3. Next, we need to convert the feet into inches. Since 1 foot is equal to 12 inches, we can multiply the number before the parentheses by 12. Thus, 1(0?) feet is equal to (1 * 12) + (0? * 12) inches.

4. Now, let's solve for the value inside the parentheses. Since we know that 1 foot is equal to 12 inches, the value inside the parentheses must be a whole number between 0 and 11, inclusive, in order for the equation to be true.

5. Finally, we can substitute the value obtained in step 4 into the equation and solve for the missing inches: (1 * 12) + (0? * 12) inches = 30 inches.

With all the necessary information, we can calculate the value of the expression.
