Thursday: Miss MaryDoll's Marvellous Maths Masterclass.

I now see that the algebra method would have saved me the guesswork in my method, so it would be the best way for larger numbers or more complicated problems. Thanks Willa!

Thanks Marydoll and Doodle! I really, really tried not to peek, but couldn't help seeing a lot of answers, so had to overcompensate by providing more solid 'proof'.
Marydoll, sorry you're 'under the weather. Hope you're better tomorrow, so we can all tackle yet another happily anticipated challenge!

Wila, my heartfelt apologies for missing your excellent explanation. My only excuse, I haven't been too well today.

In my defence, I did start the algebraic equation, but just couldn't concentrate!
You can have ???? and the eggs! Bathesheba took the flour.

See you all tomorrow.
Granny Somerset, will be sitting in isolation tomorrow!

willa wow you really know your algebra. I wish you could get in earlier so I could copy your answers. Miss would be well impressed.
squiffy hope your dog is ok and not ill after eating my sandals. I didn’t mind really I don’t like them. ?
Miss I hope you’re feeling better.
Miss I bought you an Easter Egg ......but it hatched ? !

Ooh Miss, can I have some flour please Miss? Then I can make a flour bomb for when the head teacher comes in

GrannySomerset you can sit next to me tomorrow as long as you promise to tell Jeffrey in year 8 that I fancy him

Bathsheba, thank you so much for explaining the process.
??for you, as a bonus, you can have either some eggs or self raising flour. I believe they are in very short supply.

I asked my daughter to pick up a chicken for me, like her father, she isn't so good at following a shopping list.
She left a large turkey at the back door.

You are invited to Easter dinner with all the trimmings (I'll have to get rid of it somehow). Just remember the two metre rule and spread yourselves about!?

Hopefully I will be back on form tomorrow!

Stop cheating, GrannySomerset, I saw you copying from Bathsheba
But I won't tell Miss

Thank you Bathsheba. Can I sit next to you tomorrow?

Bread is 14 because 2 of them is 28. So take bread away from right hand image and you have 1 wine + cheese = 18.

In the left hand image 2 wine + cheese = 30. Therefore it follows that the extra bottle of wine is 12 (30-18). Leaving the cheese at 6.

I'm here.....whew! What? She's handing out prizes already? Can I at least make the a case for leniency! Six hours ahead of me and I have to play catch up

OK here goes:
Image represents three different equations:
2x +z =30
2y = 28
x+y+z=32

Solved for Y first
2y = 28
y=28/2
y= 14

Solve for Z:
2 (18-z) +z = 30
36 - 2z + z =30
-z = 30-36
-z = -6
z= 6

Solve for X next (substituting values of y and z):
x + 14 + 6 = 32
x + 20 = 32
x = 32-20
x=12

12 oz bottle
14 oz bread
6 oz cheese

Miss , I finished mine ever so early and the rest probly just copied me, but my dog ate the answer.

Here’s an apple for you ......?

Sorry, I followed instructions and answered before reading any further and was expecting Miss to come along with the answer at 7 pm which is 8 pm our time. It's only just 6 pm now.

Once I'd figured out the bread was 14 oz (half of 28), and that the other two items therefore had to add up to 32 - 14 = 18 oz, I just took consecutive even numbers from 30 until I had 2 which added up to 18.

Even numbers for the weight of the cheese because I wasn't expecting fractions and 30 is an even number so the weight of 2 Wine bottles together would therefore have to be a whole even number.

I could have done it by algebra but the thinking would basically have been the same.

Cheese is 6 oz, wine is 12 oz, bread is 14 oz.

The bread was 14 each which made it easy to work out the cheese and wine/ketchup.

Doodle I was too to bring the dog today after yesterday's shameful 'performance'! I didn't think Miss Doll would be able to cope with an encore!

I’ll explain how I got the answer Miss I kept trying different numbers till I found a combination that worked ?
I failed maths too. Sorry Miss.
Hope your headache is better Miss. Have I just made it worse? ?

Oh no.
I wrote it down wrong. I did get it honest.
Bottle=12
Cheese=6
Bread=14

PS I know no one cares. ?????

Bottle =14
Cheese=6
Bread=12

Doodle will you stop sucking up to
??‍?. ???

You got the prize yesterday. What was it ?

Gold stars for all of you.?

For an extra star, would anyone like to explain how they got the answer?

Please miss I don’t know how to work this out (O level maths failed) so need an explanation. Then I might be able to attempt tomorrow’s puzzle. I do words rather than numbers,
.

Wot a clever class we are. Do you think Miss will give us all a gold star #everhopeful ??

And I bet you can still recite them Callistemon can’t you? !!
We recited our tables every single morning at primary school and they kind of sank in without us realising.

Do children still do that I wonder?

Well it looks like a Heinz ketchup to me Bathsheba and whaddaya mean “an alcy like the rest of us” ? It’s been over 40 years since I was last caught sitting behind the pub wall drinking cider !

Thank you for waiting with me Doodle and yes miss it did take two of us to go .

We woz taught proper in our day wasn’t we?!!

JenniferEccles I don't think I woz taught that kind of exciting thing back in the Dark Ages.
It was just times tables recited every single morning.

Sorry jennifer mine was more luck than judgement.?
