I can give you are summary of how to do it. UK geometry is somewhat different to US with regard to symbols used and names.
You need to prove that the 2 triangles BCE and ADE are congruent and then you can say that the sides are also congruent:- Sides BC and AD are equal (opposite sides of a parallelogram) Also < CBE = <ADE ( alternate angles) and < BCE = EAD ( alternate angles) So the triangles are congruent by 2 angles and the corresponding side, ( I think that would be ASA in the US).
Answer:
Let total non-fiction books = 3x
And total fiction books = 5x
After reading 6 non-fiction books, remaining non-fiction books = 3x-6
After reading 13 fiction books, total fiction books remaining fiction books = 5x-13
(3x-6)/(5x-13) = 3/4
Solving for x, we get x = 5
So total non-fiction books = 15 and fiction books=25
So total number of books bought = 40
Answer:
9n + 13
Step-by-step explanation:
(54n + 78)/6

(54n)/6 = 9n
(78)/6 = 13
9n + 13 is your answer.
