<span>You would have to wait 318 years for 1/5 (20%) of the Radium to disappear. 1590 is the point where half of the Radium would decay, so if you take 20% of that, it would equate out to 318 years. Radium has a long half life!</span>
Answer:
x = 3.5 is not a solution
Step-by-step explanation:
3x +2 < 12
Subtract 2 from each side
3x +2-2 < 12-2
3x< 10
Divide each side by 3
3x/3 <10/3
x < 10/3
x <3.3333333
Any number greater than 3.3333 is not a solutions
3.5 is not a solution
(3,5) should be your answer .. this is because if you translate the shape up 7 units that means you have to move it up 7 lines .. so if u are to move the shape up 7 lines the marked dot should land on the spot (3,5)
78 times 42=3,276
72 times 53=3,816
3276+3826=7102
