Answer:

A = 7

Step-by-step explanation:

7x² - 14x + 6 = 0 ( subtract 6 from both sides )

7x² - 14x = - 6 ← factor out 7 from each term on the left side

7(x² - 2x) = - 6

then A = 7

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is
Scorpion4ik [409]

Answer:

  • 26 ounces of 55% solution
  • 104 ounces of 80% solution

Step-by-step explanation:

Let x represent the quantity of 80% solution. Then 130-x is the amount of 55% solution. The total amount of salt in the mix is ...

  0.80x +0.55(130 -x) = 0.75·130

  0.25x = 0.20·130 . . . . . . . subtract 0.55(130)

  x = 0.20/0.25(130) = 104

  130-x = 26

She should use 26 ounces of 55% solution and 104 ounces of 80% solution.
