A board is 87 cm in length and must be cut so that one piece is 21 cm longer than the other piece. Find the length of each piece. Round your answers to the nearest centimeter, if necessary. * + 21?​

A board 22 cm long is cut into two pieces. One piece is 4 cm longer than twice the length of the other piece. Find the length of each piece.

A:

Piece:: x cm Other Piece:: 2x+4 cm Equation: x + 2x+4 = 22 3x = 18 x = 6 cm 2x+4 = 16 cm Cheers, Stan H.

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 k side
