Answer:

x = 16

Step-by-step explanation:

<u>Step 1:  Add 79 to both sides</u>

10x - 79 + 79 = 2x + 49 + 79

10x = 2x + 128

<u>Step 2:  Subtract 2x from both sides</u>

10x - 2x = 2x - 2x + 128

8x = 128

<u>Step 3:  Divide 8 from both sides</u>

\frac{8x}{8} = \frac{128}{8}

x = 16

Answer:  x = 16

Leviafan [203]

Answer:

332,193 years

Step-by-step explanation:

From the question above, we are to calculate the time in an half life question, hence, the formula is given as

t = In(Nt/No) ÷ -(In2/t½)

Where

t = time is takes for an substance to decay or reduce

Nt = Amount of sample after time = 2g

No = Initial amount of sample = 20g

t½ = Half life = 100,000 years

Hence,

t = In(2/20) ÷ (In 2/ 100,000)

t = 332192.80948874 years

Approximately = 332,193 years
