Halla la diferencia de 2 numeros si su mcd es 48 y su suma es 288

    SUM:                x + y = 288

DIFFERENCE:   +  x - y =  48

                            2x     = 336

                             x      = 168

 SUM: x + y = 288  →   (168) + y = 288   →   y = 120

120, 168

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)

the answer is c
