Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
(2/5) of (2/3) of students = 4/15 of students study French. Then 1-(4/15) = 11/15 of students do not study French. The ratio you want is
(4/15):(11/15) = 4:11
_____
In a math expression "of" means "times".
Answer:
14
Step-by-step explanation:
7/5. = x/ x- 4 (the ratio to each other is the same)
cross multiply
7x-28 = 5x
simplified: -2x = -28
divide x and -28 by -2
x= 14
x= # of girls
the answer is D. All points to the left of zero are negative.
