Circle the values that are solutions of the inequality 2x - 3 < -9 circle all that apply

x < -3

Step-by-step explanation:

2x - 3 < -9

Add 3 to each

2x - 3+3 < -9+3

2x < -6

Divide each side by 2

2x/2 < -6/2

x < -3

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
