10 liters of a 20% acid solution are mixed with 30% acid solution. Which of the following is the percent of acid in the final mixture?

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

i think the answer is a p = 78
