Einsteinium-253 is an element that loses about 2/3 of its mass every month. A sample of Einsteinium-253 has 450 grams. Write a function that gives the sample's mass in grams, S(t), t months from today.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

the radius is 2 times the diameter.
