7x+2y+4

Step-by-step explanation:

combine like terms:

8x-x=7x

-2y+4y=2y

3+1=4

so the simplified form of the equation is 7x+2y+4

there are no short passages to look at

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)
