What kind of problems or what are you trying to ask?
Answer:
~Re-write the equation~
SOLVE:
5x(3)+4x (2-9)+(2x+1)+(2x2+x-3)
5(1)(3)=15
4(2-9)=8+36=44
2x+1=3
2x2+x-3:4(1)-3=1
15+44+3+1
ANSWER=63x
Step-by-step explanation:
I wasn't quite sure because of the way you wrote it but here's an answer!
Mixing the two concentrations would give a new concentration which is in between 50 - 60% .
