Answer:

$\frac{1}{2}$

Step-by-step explanation:

The half life is the amount of time it takes a substance to decay to half of its original amount.

Since the radioactive substance has a half life of 1000 years, there will be half of it left after 1000 years.

So, the fraction that will be left after 1000 years is $\frac{1}{2}$

Solve for X.<br> X = [?]<br> 5x - 16 X + 10

Aleks [24]

$\boxed{ \sf{ \color{purple}\huge Answer :}}$

$\: \:$

$\large \tt \purple↪ \: \: \: \: \: 5x - 16 = x + 10$

$\: \:$

$\large \tt \purple↪ \: \: \: \: \:5x - x = 10 + 16$

$\:$

$\large \tt \purple↪ \: \: \: \: \: 4x = 26$

$\:$

$\large \tt \purple↪ \: \: \: \: \: x = \cancel\frac{26}{4}$

$\: \:$

$\underline{ \boxed{\large \tt \purple↪ \red{ \: \: \: \: x = \frac{13}{2} }}}{ \large✓}$
