Answer:

1.25 g

Step-by-step explanation:

Given:

Initial mass is m = 80 g.
Half life = 10 days
Total time = 60 days

Number of half-life periods:

r = 60/10 = 6

Equation for remaining sample:

s = m*(1/2)^r
s = 80*(1/2)^6 = 80/64 = 1.25 g

Solve the system of linear equations by substitution. 2x-y=3 x+5y=14

adoni [48]

Let 2x – y = 3 ——— equation 1

Let x + 5y = 14 ——— equation 2

Making x the subject in eqn 1, = x = y + 3 / 2 ——— eqn 3

• Put eqn 3 in eqn 2

(y + 3 / 2) + 5y = 14

6y = 14 – 3/2

6y = 25/2

y = 25/12

• put y = 25/12 in eqn 3

x = (25/12 + 3/2)

x = 43/12
