3/4(x) − 1.72 = −6.82

x = - 6.8

Step-by-step explanation:

Solve for 3/4(x) − 1.72 = −6.82

3/4 (x) = -6.82 + 1.72

3/4 (x) = -5.10

x = 4 * -5.1  / 3

x = 4 * - 1.7

x = - 6.8

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)
