Hi I was wondering how you would do question 5 on homework 2

Hi Teigan

Apologies for the slow reply, I have been unwell.

You must create an equation and solve for b. Both boys have the same amount of money or items plus money. So basically find and expression for John and a separate one for Ahmed then make them equal to one another.

I hope that helps.

Me Mac

I still don’t understand how to find out the cost of one? and also I’m not sure how to do question 6 on homework 2 because it says (-2,10) ?

Ok Teigan

We can sit down in person and go through Q5, please don’t worry too much. Q7 has the coordinate (-2,10), is it that question you mean? Q6 is different.

Q7 – Draw a coordinate diagram for this, including a negative x-axis.

Mr Mac

h I was wondering hoe to do all of question 3 and 5 I have forgot.

never mind I have got it, but see for question 2 do you use FOIL?

Hi Chloe

Apologies for the slow reply, I have been unwell.

You must use Foil at some stage but remember to separate the necessary brackets and take care with negatives.

Mr Mac

Mr Mac

hi mr. Macintyre, some of the answers are missing for me.

Hi Jenijo

Apologies for the slow reply, I have been unwell.

Answers for what?

The blue cours revision BF-answers

Hi Jenijo

I am sorry about the lack of access to the answers, it may just be a computer system issue. I will have the answers when you return but I cannot print a copy for everyone.

Make a note of any problem areas and I will ensure we have time to sit down and go through them before the test. Also, can I apologise3 for the late reply. I have been unwell and unable to access internet due to being on holiday and busy with personal tasks.

Mr Mac

Hi, could you please help me with Question 5 on homework 2.

Hi. I was wondering how to do question 5 on homework 2

Hi. I was wondering how to do question 5 on homework 2

Hi

First of all can I apologise3 for the late reply. I have been unwell and unable to access internet due to being on holiday and busy with personal tasks.

For Q5 you must create an equation by using letters (for unknown values) and numbers. The equation can be best tackled if you read each section in a broken manner.

i.e. 2 bars of chocolate = 2b or 2x

Mr Mac

Hi, I was wondering if you could help me on revision BF1 question 1,2 and 3? I have forgot how to do it.

Hi Chloe

No problem at all, they are short questions and we are better tackling them in person when we return to school. Continue with the rest of the revision and we can use the personal notes you take as a guide for revision.

Mr Mac

ok, thank you!

Yes for question seven the co-ordinates are (12,9) and (-2,10) but if I do a co-ordinate diagram how could I go along the x axis to positive 12 when the x axis are negative numbers?

I see what you mean Teigan but you are making it more difficult that it needs to be. Ignore the fact that they are negative, the negative numbers on coordinate diagrams simply describe what direction they are in.

The horizontal distance is the difference between 12 and -2 which is 14.

Do I just do it normally then? Because when I do there isn’t any space to draw the triangle it’s like a straight line and what would I do with 14 or is that just the distance

That’s just a length yeah. And the vertical distance is 1, the difference between 10 and 9.

Then join the lines to make a right-angled triangle.

Join the lines of the co-ordinates or 14 and 9 what would I write to show the 14 and 9?

A diagram Teigan

Hi mr. Macintyre see for the revision BF1.8 would the answer be x=12 ?

Hi Jenijo

I can’t seem to access the sheet on my phone. I will check the answer for you at school.

Continue to attempt the questions, the method is just as important as the answer.

Mr Mac

Hi I was wondering how would you do Question 7 on the homework? I am struggling with it a bit.

Hi Katie

You need to draw a coordinate diagram, plot the points and create a right angled triangle.

Mr Mac

Thanks for the reply but I am still stuck on how to create the right angled triangle.

Speak with me in class, try not too worry too much and thanks for taking the time to let me know.

Hi, can you help me with question 5 please?

You must create one equation by reading through the question in stages. Give the unknown value a letter.

Mr Mac

Okay, but I’m still kind of stuck ?

Speak with me in class, try not too worry too much and thanks for taking the time to let me know.

Hey.

I ran into a bit of trouble with BF1.7, and I was wondering how to do it.

Hi Mr MacIntyre i am not so sure what to do for the revision on BF1.10 question 2 I am not sure how to find x

Show me in class Kayleigh but in good time please.

Hi I have tried to do q5 but keep getting confused

Ask me in class Ciaran, you could have spoke with me last night at supported study also.

Hi mr. Macintyre I was revising BF3.3 Q1 (f) and I was wondering what you would do if its a6xa3

because I thought it would’ve been a squared then a nine at the top but the there would be the squared sign in the way… could you please help me?

Just a9 Jenijo. No squared!

hi mr. Macintyre I was wondering If you could help me with BF4.3 I don’t remember doing anything like this and don’t really understand what the question is asking?

Also I attempted doing BF4.2 Q 2. (B) I wrote as numeracy results increase so do literacy results.

would that be right ?

Hi Jenijo

I’m so sorry but my app doesn’t seem to pick up the document very clearly. I am unable to access a laptop at the moment. Could you give me more specifics RE the questions??

Thanks for your efforts.

Mr Mac

Hi mr. macintyre on BF4.3 The question is ” which of the following examples of discrete data, and which are examples of continuous data.

(a) The number of red cars on a road.

(b) The weight of a blue whale.

(c) The height of a two year old child.

(D) The number of people in 3s1 who like salt and vinegar crisps?

I didn’t really understand that question or what i was supposed to do.

We haven’t covered this Jenijo.

For BF4.2 Q2. (B) it says “describe the correlation between the literacy and numeracy marks.” i wrote as numeracy results increase so do literacy results because when i drew the scatter graph the line was going upwards so i thought it was a positive correlation, but i was a bit unsure. I appreciate the help, Thankyou.

Again we haven’t covered Statistics. Don’t worry about it.

Hi I need help on BF1.10

I can’t remember how to find x

Can you be specific Kirsty? I can’t seem to access the revision sheet.

It’s asking you to find the value of x, when the area of the rectangle is 87 square centimetres. The length of the rectangle is 3x-7 and the breadth is 5.

Hi could you help me with BF1.10 Q1 and 2

Can you tell me the questions in detail Ciaran?

it says “the shape shown below is made from a small rectangle cut from a larger rectangle. if the shaded area is 87 square centimetres, find the value of x. also do we not do BF4 or 5 in the test which is statistics, graphs,charts and probability. rotations and transformations.

No none of that is covered Ciaran.

Show me the other question tomorrow.

Okay thank you

hi Mr Macintyre please can you explain surds to me in class tomorrow I’ve had a look online but i don’t understand it because i was away on Thursday and i need to understand it for the test and i wanted to ask if everything in the booklet was going to be in the test because there are more things in the booklet that we did not do in class thanks

Hi, I was wondering if you could please help me with BF2.7 Question 3 in the revision sheet the question is; Complete the following calculations and give your answers correct to 3 sf a) 17 divided by 9 b)7% of £125000 and c) find the circumference of a circle with the diameter 4.15cm

I’m confused with question C

thank you.

Hi, I was wondering how you would do:

5-3(x+2)=14

Sorry I forgot to add, I’ve broken the brackets, but I was stuck on the next line of working.

5-3x -6 = 14

-3x = 15

X= -5

I was looking back on the revision but I don’t understand BF2.7 Q3 could you help please

Are you sure we have covered it Teigan?

Can you be specific? I can’t access the file at the moment.

It is – complete the following calculations and correct your answers to 3sf

A) 17 divided by 9

B) 7% of £125000

C) Find the circumference of a circle with the diameter of 4.15 cm

That is purely to test significant figures Teigan.

Hi Mr MacIntyre i was looking over the note you gave us for surds and i saw a question saying square root 4×9 what would you do if both of the numbers can be simplified

That would be root 36 which is 6 Kayleigh and or it’s root 4 times root 9 which again would give you 6.

thanks i am also stuck on 2/3root4 and we would have to rationalise it and simplify it

Root 4 is 2 Kayleigh. Which would give you 2/6, that doesn’t sound like the correct question tho.

See for question 1 on BF1.9 in the revision book do you flip the sign round if its two minuses ?

You flip the sign around if you multiply or divide but a negative Lucy.
