Just split it in to three rhombuses and then split each rhombus in half.
You will now have six triangles
Amount financed
320-20=300
Total paid
34×10=340
Interest
340-300=40
Interest rate
((2×12×40)÷(300×11))×100
=29.09%
Hope it helps
Since there are 60 minutes in 1 hour, the expression would be 60h.
For example, if you want to know how many minutes are in 3 hours, just substitute 3 into h: 
--> 
minutes

Answer:
There were 30 children and 10 adults.
Step-by-step explanation:
Since they sold tickets to adults and childrens, the sum of those tickets must be equal to the total tickets that were sold, so we can mount our first equation as shown below:
adult + children = 40
Each adult ticket costs $9 and each children costs $5 and the total recieved was $240, therefore:
9*adult + 5*children = 240
We can mount the following equation system:
adult + children = 40
9*adult + 5*children = 240
We will multiply the first equation by -5 and sum both equations:
-5*adult -5*children = -200
9*adult + 5*children = 240
4*adult = 40
adult = 40 / 4
adult = 10
adult + children = 40
children = 40 - adult = 40 - 10 = 30
There were 30 children and 10 adults.
