You break it down into steps. FIrst do the X's. 5x-3x=2x Then you add 18 to both sides and your equation looks like this 2x=22 Divide by 2 on both sides and x=11

Answer: 31/25/50
Explanation: 31 is the second one. 6 less than second is 25 which is the first one, and third is 2x the first so 50
50 + 25 + 31 = 106
The answer I have is B and D, I hope that this helped.
Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"
Suppose n is even. That means n = 2k where k is any integer.
Square both sides
n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)
The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even.
So this contradicts the initial statement which forces n to be odd.
