Step-by-step explanation:
As values are missing in your question, the complete question is:
In the lab, Leila has two solutions that contain alcohol and is mixing them with each other. Solution A is 6% alcohol and Solution B is 20% alcohol. She uses 400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 12% alcohol solution?
Considering x=ml of 20% solution B
Therefore, 400+x=ml of resulting 12% solution
Solution A alcohol+ solution B alcohol= Alcohol solution
6% (400)+ 20%x = 12%(400+x) ->(converting percentage into decimal)
.06*400+.2x=.12(400+x)
24+.2x=48+.12x
.08x=24
x=24/.08=300 ml
she used 300 milliliters of 20%Solution B in resulting mixture.
The answer is C- 99.5ft :)
Hello :
<span>f(x) = 4x − 5 and g(x) = 3x + 9
</span><span>(f + g)(x) = f(x) +g(x) = (4x-5) +(3x+9)
</span><span>(f + g)(x) =7x +4
</span><span>(f ⋅ g)(x) = f(x) × g(x) = (4x-5)(3x+9) = 12x² +36x -15x-45
</span>(f ⋅ g)(x) = 12x² +21x -45
<span>f[g(x)] = f(3x+9) = 4(3x+9) -5
</span><span>f[g(x)] = 12x +31</span>
Unit price is the price for 1.
