The answer would be 2n^2+3n+ 8n-1
Answer:
5.714 liters of the 5% solution and 4.286 of the 40%.
Step-by-step explanation:
Let x be the volume of 40% solution and y = volume of the 5% solution.
x + y = 10
0.40x + 0.05y = 0.20(x + y)
From the first equation x = 10 -y so we have:
0.40(10 - y) + 0.05y = 0.20( 10 - y + y)
4 - 0.40y + 0.05y = 2
-0.35y = -2
y = 5.714 liters of the 5%.
and x = 10 - 5.714 = 4.286 liters of the 40% solution.

Answer:
720,080 = 700,000 + 20,000 + 80 =
7 * 100000 + 2 * 10000 + 0 * 1000 + 0*100 + 8*10 + 0*1 =
7 * 10^5 + 2 * 10^4 + 0 * 10^3 + 0* 10^2 + 8 * 10
