Answer:

C) 25%

Step-by-step explanation:

let salt be 's'

let water be 'w'

$\frac{s+1}{w+s+1} = 33\frac{1}{3} \\\\\frac{s+1}{w+s+1} = \frac{1}{3} \\\\\frac{w + s + 1}{3} = s+1\\\\3s +3 = w+s+1\\w = 2s+2\\\\\frac{s+1}{w+1+s+1} = \frac{3}{10} \\\\\frac{3(w+s+2)}{10} = s+1\\\\3w+3s+6 = 10s+10\\**w = 2s+2\\3(2s+2) + 3s + 6 = 10s+10\\\\6s+6+3s+6 = 10s+10\\9s+12 = 10s+10\\-s = -2\\s = 2\\\\w= 2s+2\\w=2*2+2\\w = 6\\\\\frac{2}{2+6} = \frac{2}{8} = 0.25$

0.25 = 25%

Find the inverse of the functipn <br><br> f(x)=3x-7/2

vivado [14]

Answer:

2x+7/6

Step-by-step explanation:

an normal function would be mapping x to y, since this is the inverse we would map y to x

f(x) and y are the same so I will take f(x) as "y"

1)3x-7/2=y

3y-7/2=x

solve/isolate "y" in 3y-7/2=x to get the value of "y"

3y-7/2=x

add "7/2" to both sides

3y-7/2+7/2=x+7/2

3y=x+7/2

divide both sides by "3"

3y/3=x/3+7/2/3

simplify:

y=2x+7/6

hope this helps!

HELP A FRIEND IN NEED

Leokris [45]

Answer:

Angle A = 68 degree

Angle B = 44 degree

Step-by-step explanation:

Sum of all interior angles = Angle A+Angle B+ Angle C

180 = 68+x+x-24

180 = 68+2x-24

180-68 = 2x-24

112+24 = 2x

136/2 = x

68 = x

Therfore, Angle A = 68 degree

Angle B = (x-24)

= (68-24)

= 44 degree
