Answer: 54.6
Step-by-step explanation:
The answer may be c.
I am not clear about your question.
9x^2-12x-5=(3x-5)(3x+1)
Let's thing
949 ----- 100% of the price
499 ------ x% of the price
Multiply in cross
949.x = 100.499
949x = 49900
x = 49900/949
x = 52,58%
So, rounding it 52,58% ≈ 53%
Alternative B
Part to part ratio is oranges to bananas, so: 2:5
Part to whole ratio is oranges to all fruits or bananas to all fruits.
Oranges to all fruits would be 2:7
Bananas to all fruits would be 5:7
Hope that makes sense
No.....the correct calculation would be : 27 x 5...then add 25
