First you must relate each triangle to the model that you have to get the answers within each triangle. Then find some pattern that makes them relate in some way.

each triangle is it own problam in a way. and each mini triangle it in a big triangle so you could find each trianglesproduct and multiple erything

I'd just find the product of each triangle and then add em together.

Hallie said...

The top number is A and you multiply that by the number on the bottom left. then subtract the number on the bottom right by that. then add them on together maybe?

each triangle is it's own problem and there are four tringles like the abc one so then you would take the first traingle the whole thing and 3 the A times 5 the B - 2 the C so that is 13 and then you would do the same for the rest of the triangles. I think?

Find the answer to each of the triangles. Like:
3 x 2 - 1 = 5
4 x 5 - 3 = 17
1 x 7 - 2 = 5

Then find the answer for that...
5 x 17 - 5 = ?

I think you have to do
3*2-1
4*5-3
1*7-2
3*5-2
add them up

The answer to the rule for the top triangle will yield a number. This will become the number to go in the top of the large triangle. Do the same for the other three and then you have three answers (the answer to each triangle). Now perform the operation again.

I would take the function from the ABC triangle and relate it to the bottom triangle. 5
20 5

Then relate the function to this. 5*20-5= 95

each triagle does the ABC order but then u take the product of all that and do the problem again with the product of the first triangle be A and the second be B and the third be C.

I think that you have to solve all of the triangles that you can and then see how the all relate. Then you can find the blank one.

Mrs. Cooper said...

Yvonne explained it great!
so the answers for each triangle are 5, 17 and 5.
These become your new a, b, and c.
So...
(5)(17) - 5 = 80!

I think that you have to insert the #'s into the equation for the letters. A would be the top #, B would be the # on the left, and C would be the # on the right.
