una vela triangular de una barca se ha estropeado y hay que sustituirla por otra. para confeccionar la nueva vela nos cobran 21 euros por m² ¿cuanto costara esa nueva vela si debe tener 8 m de alto y 4 m de base?

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)

you can't solve x because it is 2 linear equation and you only have one equation
