    ahhhhhhhhhhh.THANKS!!!!! now i can do my homework! Thank you :)

  • Gemma

    but ermmm what does it mean?

  • Mrs Tibble

    Just draw the triangles! It’s only telling you what type of info you have been given to draw them.

  • Ellen Partinngton

    Mrs Tibble, how many solutions are there to the symmetrical times homework?

  • Mrs Tibble

    Hi Ellen,
    I make it eleven, how about you?
    Mrs T

  • Isadora

    I make it 12 and my mum checked it

  • Mrs Tibble

    Go Isadora!!

    I’ll get back to the drawing board then lol

  • Aalia

    Hey, can you please help me on question 6 page 377 on 9A book? i dont understand where the angle of 8 goes, and if i use cos or tan! thaankkyou

  • Aalia

    sorry wrong page!!

  • Mrs Tibble

    Aalia, haven’t you realised you aren’t in year 7 any more?!!

    What does ‘horizontal’ mean? The 8 deg is the angle between the slope and the horizontal. The side you need to find is the vertical one. Once you have drawn the triangle and marked the angle, you’ll be able to label your sides. Then use SOH CAH TOA to decide which one to use.

    I can only think of 10 EEERRRHHHH!!!!!! this is soo fustrating.

  • Aalia

    thank you, i get it now, and sorry!

  • Mrs Tibble

    Imogen,
    Work out which numbers actually can be reflected, then work systematically with the combinations, remembering that you have to have real times. There are definitely 11 but I can’t find Isadora’s twelfth yet :-(

  • ImogenPontin

    YAY!!!
    i found 11 now i’m trying to find 12 like isadora xx

  • Mrs Tibble

    Good luck!!

  • Bella Hudd

    HI I’m stuck on question 4a on the homework.

  • Mrs Tibble

    Hi Bella,
    Use some tracing-type paper to help you. Copy the diagram into your book. Trace the pink shape then pin the tracing paper down somewhere with your pencil and rotate the paper to see if the shape then lies on top of the orange one. If it doesn’t, pin the paper down somewhere else. Keep trying till you find the right point for the centre of the rotation.
    JT

  • Mrs Tibble

    Bella,
    Sorry – just realised I was looking at the red shape, not the orange! 4a isn’t a rotation as it doesn’t turn: it’s a translation.

  • Wow! No-one has written on the maths blog for almost a month. Well… apart from me: now….

  • Mrs Tibble

    Hi Emmanuelle,
    Other year groups have, just not year 7!

  • Naaaaaadia!!!

    Hi Mrs Tibble, was just wondering when our maths exam is, thanks, Naaaaaaaadia :-D

  • Mrs Tibble

    Hi Naaaaaaaadia ;-)

    The exams are after half term, so stop panicking lol!!

    If you mean the Maths Challenge, it’s not an exam. (but it’s on Thursday) I’ll tell you about it in tomorrow’s lesson.

  • Isadora

    Mrs Tibble we’ve already done this homework shal i do it again?

  • Isadora

    Sorry Shall

  • Grace

    We’ve already done the homework you’ve set us. I’m really confused. I don’t think I’ll do it again.

  • Zile

    HIIIIIIIIIIIIIIIIIII!!!!!!!!!!!!!!!!!!!!

  • Mrs Tibble

    Hehe! Must be your lucky day then Isadora. You can have the night off 8-)
    You too Grace.
    Wonder how many people will realise?

  • Gemma

    Hi Mrs T! Sorry if you were expecting me yesterday. It’s just that I had to go to the dentist. Ermm, I’m kind of stuck for the first question. I just don’t get what “Multiply out the brackets” means. Do you have the H/W book? If not the first question is:
    Simplify these expressions by multiplying out the brackets:
    3(x+8)
    HELP!!

  • Gemma

    Actually, no, forget what I wrote. I erm managed to work it out, sort of.

  • Gemma

    OK. I am stuck on Q7. I have done it but I am almost completely sure that I have got it wrong. Have you got the H/W book?

  • Mrs Tibble

    Hi Gemma,

    If the red rod is x+5 long
    then 3 red rods must be
    3(x + 5)
    so that’s part (a) done.
    Part b is multiplying out the bracket
    so 3 lots of x plus 3 lots of 5

    Does that help?

  • Hi Mrs T,

    I am sooooo cufuzzled! I think I understand Q4 of the homework. And Q5 is fine too, but then Q6 is really making my mind like a wirlwind if you get what i mean. I’m not really sure how you multiply the brackets out. Yeah so ummmm please wirte back A.S.A.P. Thanks ! Also how do you do the smileys. It doesn’t work. :D See :) or that :( or that!

  • OMG! This is so annoying! I just wrote about a paragraph and my computer’s just deleted it. ARGHHH!!! TECHNOLOGY!!!1

  • Oh it did work.! ARGHHH TECHNOLOGY! Hey the smileys worked too.

  • Mrs Tibble ???????????

  • Gemma

    yeah thanks but i got a really different answer. for part a i got 3(x+15) and 8(y-16)!

  • Gemma

    Wait, actually, I don’t understand if 1 rod is x+5 then shouldn’t 3 rods be 3x+15, because it is 3?

  • Mrs Tibble

    Gemma – yes. 3 of everything; that’s what brackets are all about.

  • Mrs Tibble

    Emmanuelle,
    Sorry – been at school.

    x(x+2) means multiply everything inside the bracket by the x outside the bracket.

    x times x is x-squared
    x times 2 is 2x
    so the answer is x squared plus 2x

  • Naaaaadia!!! :-D

    Hi Mrs Tibble,

    sorry this is a bit late, I had a rounders match, so got back home really late. For the homework, I was doing the puzzle, and I’ve already completed my homework limit, and my brain is going mental, ahhhhhh! Anyway, I’ve come to a conclusion that the number of eggs has to end in a 1, otherwise, 5 will not work, and it has to be odd. I’ve tryed so MANY things, but they’ve all brought me back to square one, which is very unfair, because this was one of the few times that I set my homework out neatly… Please help!!!

  • Mrs Tibble

    lol Naaaaadia! Sorry it’s even later now cos I’ve only just seen this!
    Yes it does have to end in one; it also has to be a multiple of 7.
    See you tomorrow!
    Don’t stay awake counting eggs ;-)

    Hi Mrs Tibble,

    am really confused, cos am not sure what to do: when you’re trying to work out the equation, does bodmas/bidmas take priority??? Example: The area of a rectangle is 120cm squared. The width is 5cm and the length is 5x + 4cm. The equation would then be 5 x 5x + 4cm, so do you do the 5x + 4cm, or the 5 x 5x???? would it make any difference????????????????? am very confused…..??….???…….

  • Gemma

    Hi Mrs Tibble, I am really stuck on Q5 c. Do you have the book? Please write back ASAP; Thanks!!!!! :) ;)

  • Ameera

    Hi Mrs Tibble I am stuck on P67 Q7 part B. On part A I put 3(n+4)=5n-4 but I don’t know how to solve the equation! Help please???

  • Mrs Tibble

    Nadia,
    You need to put a bracket round the 5x+4 ie it’s 5 lots of everything.
    JT

  • Nadia

    ohhh!!!!! Thanks!

  • Mrs Tibble

    Hi Gemma,
    If 3 lots of the bracket is 24, then the bracket must be 8.
    JT

  • Mrs Tibble

    Hi Ameera,
    What you have done so far is correct – well done 8-)
    Now multiply out the bracket, then solve like you were doing today in the lesson.
    Good luck!
    JT
