When a problem has no solution you'll end up with a statement that's <em>false</em>. For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution.
The answer would be the first phrase.
3x is 3 times x, and +4 is the sum of 3x and 4.
For the half-life of a certain substance, the equation that would best represent the scenario is,
At = Ao(0.5^t/n)
where At is the amount at any time t, Ao is the original amount, and n is half-life. Substituting the known values,
At = (220 mg)(0.5^(396/72)
At = 4.86 mg
Thus, after 396 days, there will only be 4.86 mg of Terbium-160.

Answer:
C and D
Step-by-step explanation:
9% = 9/100 = 0.09 < 0.4
0.125 < 0.4
7.8 * 100 = 780 > 0.4
7/16 = 0.4375 > 0.4
