Is this a multiple choice question? If so what are the options?
My guess is 21
Answer:
30%
Step-by-step explanation:
The line is starting from right side and goes thorough left .
Means
- Its starts from 1st Quadrant and goes to 3rd Quadrant.(+ve to -ve)
- Y is infinite
Hence
The solution is
![\\ \sf\longmapsto (0,\infty]](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20%280%2C%5Cinfty%5D)
The answer is 15 : 5
because In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
And you said girls : boys
That means 15 : 5 or 15 to 5
For this case we have the following expression:
We take common factor 
, for this we must take into account that:
So, factoring the expression we have:
ANswer:
The factored expression is:
