Maths year 11

That is correct, depending on what kind of approach you are taking.

What would we find if we did this?

How do I find the number of cats? :/

Doesn't specify.

Heya, my end of year exam is coming up and I'm doing higher and I'm getting D's I'm currently in year 10 and I know I can do better if I revise. Is anyone else willing to help me with a few questions ?


In year 11 now.
Grade achieved end of year : C

That's the last thing you'd fill in.

It gives info about the total amount of males and female.

We know that $80=M+F$ where M are males and F are females, and we know that $M=F+20$ therefore we can substitute this into our first equation and find the amount of females and males altogether.

Is it like that
Sorry abit rough

Almost, not quite.

$80=(20+F)+F$

Substitute $M=F+20$ into $80=M+F$ and you would have $80=(F+20)+F$

Substitute $M=F+20$ into $80=M+F$ and you would have $80=(F+20)+F$

Substitute $M=F+20$ into $80=M+F$ and you would have $80=(F+20)+F$

Substitute $M=F+20$ into $80=M+F$ and you would have $80=(F+20)+F$

I was working on a D in maths throughout year 10 & 11 and got an A in the end, I did this through many, many past papers (same questions come up year on year) and mathswatch which I think you have to pay for but I found it really good.

Substitute $M=F+20$ into $80=M+F$ and you would have $80=(F+20)+F$

Heyaa what rule do I use for this :/

No rule - it's an isosceles triangle.

Are both sides worth 45 degrees and the top is 90?

But that doesn't add up to 360 the top one
