ReplyDeletefor anyone who understands page 1 in our hw packets this week, dont understand it at all!!!! please help!

Page one is simple, I didn't get it either until my friend explained. So for question one you have to use the formula to get the answer. Do 75 plus 30 times 2 and that is your answer for #1. #2 use area as a hint then use what you have to do to find area. #3 is finding area of right triangles. Find all the areas then add them together to get your answer and if you do the way with the formula for a triangle remember to divide by 2. *Jordan Gagnon* RIC
DeleteIn the math packet #8, what method do you use?
ReplyDelete~julia f. RIC
Dear Julia,
DeleteI think that with that question you are using PEMDAS.
Victoria DeDonato :) RIC
If you still don't get it, another method that works is using a chart. Think that you have one blueberry and go from there. Also, don't forget to write the total pieces of fruit each time you double each piece of fruit. Hope this helps.
Delete*Victoria W.* RIC*
You can also think about it like since there are twice as many raspberries as blueberries so its 2b=r. Whe nyou have that you can just continue with the others until you get to cherries. But in the beginning, you do have to solve the original problem by using these equations [2b=r.] You dp this by replacing the variables. Im writing a lot but I hope I helped!

Dear Julia,
DeleteI think you divide because there is a division sign. :)
Here is an example of a hint...
ReplyDeleteFind a way to substitute variables for one another. For example, you know that there are twice as many raspberries as blueberries, so 2B= R. You can do the same for the other fruits. Once you solve for one variable, you can solve for the rest of them.
Here is a practice question for anyone who needs it:
ReplyDeleteStella and Jason have 24 cards altogether. Stella has 15 cards. How many cards does Jason have? Write an equation and solve. Explain your answer.
-Eva L. UChicago
Equation: 15+J=24 ( Let J represent the number of cards Jason has)
DeleteAnswer: Jason has 9 cards.
Explanation: First, I wrote down the equation: 15+J=24. Then, I subtracted 15 from both sides since the rule is that what you do to one side, you do to the other. Since 15 minus 15 is 0 and 24 minus 15 is 9, after subtracting I was left with J=9 ( You don't need the 0 at this point). Finally, I concluded that Jason had 9 cards since the variable "J" represents the number of cards Jason has.

Since this was a direct question, is it okay to give the answer, or did I have to just give hints?

I have a question for anyone who wants to do it...
ReplyDeleteif i have 17 dollars and i buy 5 shirts that are 3 dollars, what is my change?
~Victoria DeDonato :) RIC
Your change is $2. :P
Delete-Elly Rourke from PC
your change is $2 because 3x5=15 so there is $17 so u can do 17-15 which would get you $2
DeleteI dont understand how to do number 8 in the first part of thye math packet. Can anyone help?

DeleteFor tenmarks, which color monster do we complete?
ReplyDelete-Elly Rourke from PC
I don't think it matters as long as you complete a monster block with more than 80%, I think your good.

For number 4, can we cross out the zeros from 150 and 50 to make it easier?
ReplyDelete-Caitlyn Quigley from PC
I know this reply is late but I wanted to answer you question.
DeleteSo, whenever you have a division problem that has zeros on both sides, you can cross them out. I don't think you can do it with any other numbers like one and nine though. Remember: What you do to one side, you must do to the other.
So, for example: For 200 divided by 20, you could cross out one zero from each side to make it 20 divided by 2. This stragety makes it much easier to solve problems. Hope this helps! :)

DeleteHere is a question for anyone who wants to answer it:
ReplyDeleteA right triangle has a base of 7cm and a height of 9cm. What is the area of the right triangle?
*Victoria W.* RIC*
on page 10 question 2, how do we find the dimensions? I already got the area of the rug to be 47.25ft squared.
ReplyDelete*Chelsea*
*RIC*
Chelsea,
DeleteThere are many different possibilities to the dimensions of this rug. If the rug was 2 feet wide, how long would it have to be? To solve that, you could use the equation lw=A, and substitute in the values you know. If the area is 47.25, and you make up that the width is 2, your equation reads as 2(l)=47.25. Solve for h. You can change either the length or height and solve the equation again.
What is 6 x 45 + 7 x 4 equal?

This is a comment from Sole
DeleteDestiny p we can not tell you the answer to the question you are asking but instead of multiplying all of the numbers together separate them. So the first thing to do is multiply 6*45 then multiply 7*4 and then when u find the product add them up and the sum of that is your answer
