Answer:
x= -2
Step-by-step explanation:
-3x-5=1
+5 on each side to balance the equation:
-3x=6
Divide by -3 on each side:
x=-2
The question is incomplete, here is the complete question:
Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.
<u>Answer:</u> The half life of the sample of phosphorus-32 is 
<u>Step-by-step explanation:</u>
The equation used to calculate the half life of the sample is given as:

where,
m(t) = amount of sample after time 't' = 356 g
= initial amount of the sample = 500 g
t = time period = 7 days
h = half life of the sample = ?
Putting values in above equation, we get:

Hence, the half life of the sample of phosphorus-32 is 
Answer:
54/120 or 108/240
Step-by-step explanation:
X = 17% of 350
17% = 17/100 = .17
Saying "of" in mathematics is like saying "multiplied by"
x = .17 * 350
x = 59.5
