PLEASE HELP Element X decays radioactively with a half life of 7 minutes. If there are 150 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 3 grams?

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

is the anwser to the question

-7.8

step-by-step explanation:

3.5 + -7.8 = -4.3

3.5 + -7.4 = -3.9

3.5 + -7.1 = -3.6

3.5 + -1.2 = 2.3
