Solve the formula for w. s=2lh+(2l+2h)w

So firstly, subtract both sides by 2LH:

Next, divide both sides by (2L + 2H):

Next, factor out 2 in the denominator and your final answer will be

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)
