Write and solve an inequality that represents the number of apples, x, you can buy if each apple costs .75 cents and you have to spend less than $9.

0.75x<9

Step-by-step explanation:

0.75x<9

0.75/0.75x < 9/0.75

x<12

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 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)
