64 ounces of a 2% salt solution contains 1.28 ounces of salt and thus 62.72 ounces of water.
The mass of the 10% solution is (x+1.28), where x is the mass of water.
1.28 divided by (x+1.28) must be equal to 10%.
The 10% solution contains 11.52 ounces of water.
51.2 ounces of water must be evaporated.
Answer:
1/4
Step-by-step explanation:
absolute value are always positive

This really depends on what the question asks, because if you substitute 0 for x, the equation comes to 0 > 0 (which is a logical error), if you substitute 1 for x, the equation comes to 0 > -5 (which is the correct answer). If you substitute -28 for x, you get 0 > 28 (and we know 28 will always be greater than 0, but 0 will never be greater than any positive number), this is the same if you were to substitute -36 for x, you get 0 > 36
So the correct answer is D.) x > 1
because you get 0 > -5 (when you plug in 1 for x), and 0 will always be greater than any given negative number...

One more thing, this question is asking you to MAKE IT TRUE, IF it said 0 ≥ -3x - 2x... THAN A, B, and C would be correct, OR IF it said 0 ≤ -3x - 2x... THAN B and D would be correct, BUT because it only says 0 > -3x - 2x... THAN ONLY D is correct...
With a simple change of signs, you can dramatically change the answer to this equation
Answer:
your right it is a rational number
