X = -2(5 + (sqrt34)) OR 2((sqrt34) - 5)
Answer:
200 mL
Step-by-step explanation:
If x is the volume of solution B:
0.06 (500) + 0.20 x = 0.10 (500 + x)
30 + 0.20 x = 50 + 0.10 x
0.10 x = 20
x = 200
Answer:

Step-by-step explanation:
Solve for p:
i = prt
i = prt is equivalent to prt = i:
prt = i
Divide both sides by rt:



Answer:
125%
Step-by-step explanation:
This because if in origin the city was made up for example by 100,000 people, that was the 100% of the city. Now you add the 25% in two years and the city will be made by 125,000 people. So <em>100%+25%=125%</em><em>.</em><em> </em>
I think it's right
