3/5 * X = 15
3/5 ÷3/5 * X = 15 ÷ 3/5
X = 25
The total length is 25 miles
0+0=0 0+0=0+0
They are all addition, and they are all 0, and since 0 equals nothing, the sum is equivalent to 0!
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.
