The sum is idk really know right now but I'll get back to you with the andwer
Answer:
Step-by-step explanation:
Assume as a basis the final mixture is 1000 mL. That means 399 mL of alcohol
Let x = mL of Soln A and y = mL of soln B.
x = 2y.
Now x + y = 1000
and 0.2x + 0.17y = 399
but x = 2y so 0.4y + 0.17y = 399
0.57y = 399.
y = 700 mL (That is your mL of solution B)
the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Have a nice day <3

This Must Only Have One Solution, Because The Right Side Of The Equation Is Just Plainly Ten. Lets Solve This:
5x + 3x - 4 = 10
Add Four To Both Sides To Begin Simplifying.
5x + 3x = 14
Now, Combine Like Terms.
8x = 14
Divide:
8x/8 = 1X = X
14/8
X = 14/8
14/8 = 1.75
X = 1.75
Check:
(5 * 1.75) + (3*1.75) - 4 = 10
8.75 + 5.25 - 4 = 10
14 - 4 = 10
10 = 10.
This Is True, So X Does Equal 1.75
