I hope this is what you're looking for. The concept of regrouping<span> (borrowing) is so that students can see what actually happens in it. For example, to </span>subtract <span>52 − 38, we write 52 as 50 + 2 (breaking it down into its tens and ones). Then, </span>regrouping<span> means that 50 + 2 becomes 40 + 12.</span>
An equation to represent this would be 12x+2=T.
x=10 people per large table.
If T=122 then we just have to isolate x on one side of the equation. The first step is to replace T with 120 and then subtract 2 on both sides (to cancel the +2) to get 12x=120. Cancel the 12 by dividing both sides by 12 to get x=10. The number of people seated at each large table would be 10. Hopefully I explained this correctly and helped you understand.
Answer:
Neither
Step-by-step explanation:
I don't know how to solve 11 but I guess I can solve 12 so I think those are the answers:
12.
(4, 53)
(5, 85)
Answer:
1200
Step-by-step explanation:
Find the width and the height show in the picture then use the formula Area = length X height
The width is 40 and the height is 30. Therefore Multiply it together and get 1200
It may not be the answer!
