Hey! My teacher sent out some similar questions to what we are having on our test in a week. The problem is, I don't understand well! Just please explain these questions to me. BTW! This is not graded! I am not cheating. :) thanks heres some problems (i worked some out already but i want to know i did it correctly)

Question 1: Find the missing number. ___, 48, 12, 3 (i think it may be 192!)

Question 2: Figure out the expression: 4(x + 8) for x=6

Question 3: canned potatoes are for sale for $2.50 per can, this can be written as $2.50. Evaluate this expression if you buy 7 cans of pota

1.  192 is correct!  You found the pattern and continued it (backwards)!

2.  They want you to plug in 6 for the x in the expression, then simplify.  Can you plug it in and simplify using order of operations?

3.  The expression would be 2.50x (or p or c or whatever letter you want -- I think it got left off in your post).  So if you buy 7 cans of potatoes, you need to plug in 7 for the variable in the expression.  Then it's just like #2 -- plug and chug.

Ahh!! Thank you so much! That will prepare me for the test

I figured out that 2. Is 56 after simplifying
