That’s right. So 120 + 90 =

Olivia

6:14

Ohhh I forgot to add 90 :) thanks for helping

210

Maria Dawber

6:15

And then take it away from the total :) you are always welcome, Olivia!

Olivia

6:15

Ok :)

Maria Dawber

6:18

Jamie, on question 16 you need to divide the total (360) by how many sections

jamie

6:19

Maria Dawber

6:19

Excellent. So 360 divided by 9

Olivia

6:20

I am a bit stuck on question 30

Maria Dawber

6:21

Ok. First of all work out how many degrees are missing altogether

So 360 - 243

Olivia

6:22

=117

Maria Dawber

6:22

Perfect. Now it says that b = 2 x a

6:23

So you have a and then 2a. How many lots of a is this altogether?

jamie

6:23

i do not get it

Olivia

6:23

Oh so 2 x 117?

Maria Dawber

6:23

Jamie, how many lots of 9 in 36?

jamie

6:23

oh no D:

Maria Dawber

6:24

Olivia, if you have a and then 2a, how many lots of a is this altogether?

jamie

6:24

Maria Dawber

6:25

Correct. So how many lots of 9 in 360?

jamie

6:25

Olivia

6:25

is 2a 117x2???

Maria Dawber

6:25

No, Olivia.

117 is the same as a + b

Olivia

6:25

Oh :|

Maria Dawber

6:26

But it says that b = double a, so 2 x a

Olivia

6:26

Maria Dawber

6:26

So you have a and 2 x a, how many lots of a is that altogether?

Olivia

6:27

134 is 2xa isn’t it?

Maria Dawber

6:27

No. Have a look at the question I asked you.

Olivia

6:27

No I mean 234
