To start, she has 3 pounds of flour
She uses 1, subtracts 1 pound
Now she has 2 pounds of flour
Answer:
x, x+2, x+4
(x+2)^2 - 4(x) = 6(x + 4) + 7
x^2 + 4x + 4 - 4x = 6x + 24 + 7
x^2 - 6x - 27 = 0
x = 9 (∨ x = -3)
The three numbers are
9, 11, 13
but it could be also
-3, -1, 1
Eight times the quantity of a number and six.
8 (x+6)

Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation.
First, subtract 1/4 from both sides.
1/4+x-1/4<5/6-1/4
Solve.
5/6-1/4=7/12
Therefore, the correct answer is A. x< 7/12.
