The answer would be 90 because it takes 60 days to become a half-life so the the half of 720 is 360 the 180 then 90

If NO =17 and NP= 5x-6, find they value of x. Then find NP and OP
CaHeK987 [17]

<em>Greetings from Brasil...</em>

We notice 2 dashes on the NO and NP line. This means that both are the same size. Since NO = 17 then OP is also 17 in length.

So

NP = NO + OP

NP = 17 + 17

NP = 34

As already said

NP = 5X - 6 = 34

5X - 6 = 34

<h2>X = 8</h2>
