M is the slope.
B is the y-intercept
The constant of proportionality is the ratio between two directly proportional quantities.
Given that the half life of 3H is 12.3 years.
The amount of substance left of a radioactive substance with half life of

after t years is given by

Therefore, the number of years it will take for 18% of the original tritinum to remain is given by

Therefore, the number of <span>years that the time could be read at night is 30.4 years.</span>
If you mean turn 25/8 into a decimal its 3.125 but if u need it in a mixed fraction its 3 1/8
8+2(12-5)
here we solve the bracket part first
8+2(7)
Now multiplying 2*7
8+14
=22
Answer 8+2(12-5)=22
Answer: u<6
Step-by-step explanation:
Isolate u by dividing both sides of the inequality by 7
