The new mixture has a total volume of 5 L + 9 L = 14 L.
70% of the 5 L alcohol solution is alcohol, so that it contributed 3.5 L of alcohol to the mixture. The pure water contributed no alcohol. So in the mixture, the concentration of alcohol is
3.5 L / 14 L = 0.25, or 25%
Did u mean -8+3= and -8x3= cuz if so then it’s -8+3=-5 and -8x3=-24 so it would be -8+3
The coefficient of the second term is the 3 in (4x+3y)
When you see this kind of question use « BODMAS »
1.Add the 2 digits which is 3+7=10
2.Add the digits inside which is 0.7+1.3=2
3.Add the inside and outside
3+7(0.7+1.3)
10(2)=20
