Answer:

-3

Step-by-step explanation:

3-(7-2x) > -8

get rid of the parentheses because there is a minus sign before them

3-7+2x > -8

replace x with all the numbers (one by one not all at once) and see if the equation is correct until you find the number that makes it incorrect.

<u>EXAMPLE:</u>

3-7+2(1) > -8 parentheses next to a number means multiply

3-7+2 > -8

3-7 = -4

-4 + 2 = -2

-2 is greater than -8

Staals half
1 gram left
0.3 grams left
half lives are normally written in years
it goes likt this

A=P( \frac{1}{2})^ \frac{t}{h}
A=final amount
P=initila amount
t=time elapsed
h=time half life is (same units as time)

let's use days as the units of time


we are given
initial amount=1gram
final amount=0.3gram
time=4 days

so
0.3=1( \frac{1}{2})^ \frac{4}{h}
solve for h
0.3=( \frac{1}{2})^ \frac{4}{h}
take the ln of both sides
ln(0.3)=ln( \frac{1}{2})^ \frac{4}{h}
ln(0.3)=\frac{4}{h}ln( \frac{1}{2})
times both sides by h
hln(0.3)=4ln( \frac{1}{2})
divide both sides by ln(0.3)
h= \frac{4ln( \frac{1}{2}) }{ln(0.3)}
use calculator
h=2.30287
3 sig figs
h=2.303 days
