BaLLatris [955]

Set up a proportion
3 coins:8 notes and then the other one 24 coins : x (unknown notes)
they have a relationship so we can set them equal to each other.
3/8=24/x cross multiply: 8 * 24 = 192
Now divide that by 3: 192/3 = 64
So there are 64 notes in the bag

Work out the perimeter

Tasya [4]

Answer:

46CM

Step-by-step explanation:

Perimeter = S + S + S + S + S + S + S +S

Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2

Perimeter = 46 cm

The other 4 measurements:

5 is from the other side labelled 5 this is because they are equal.

8 is from the other side labelled 8 this is because they are equal too!

The twos are from the difference between 9 and 7.
