There was a sample of 350 milligrams of a radioactive substance to start a study. Since then, the sample has decayed by 8.6% each year. Let t be the number of years since the start of the study. Let u be the mass of the sample in milligrams. Write an exponential function showing the relationship between y and t

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
