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.
Step-by-step explanation:
The easiest way to do this is to pick your prime numbers and multiply them to get the composite number.
13* 5*5*5 *2*2= 6500
Final answer: 6500

a=48
Answer:
Step-by-step explanation:
perp. -1/3
y - 3 = -1/3(x + 2)
y - 3 = -1/3x - 2/3
y - 9/3 = -1/3x -2/3
y = -1/3x + 7/3
