let's say "x" is the whole lot and thus the 100%.

we know 12 is 60%, how much is "x" or 100%?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 12&60 \end{array}\implies \cfrac{x}{12}=\cfrac{100}{60}\implies \cfrac{x}{12}=\cfrac{5}{3} \\\\\\ 3x=60\implies x=\cfrac{60}{3}\implies x=20

A rope is cut into three pieces of different lengths. The first piece is of length x meters, The length of the second piece is 2
Iteru [2.4K]

Answer:

first piece = 5 m

second piece = 2(5) + 2 = 12 m

third piece = 3(2x + 2) = 6(5) + 6 = 36 m

Step-by-step explanation:

The question is incomplete, the length of the actual rope is unknown but it should be given . Let us assume the length of the rope is 53 meters.

The rope is cut into 3 pieces of different length.

first piece = x

second piece = 2x + 2

third piece = 3(2x + 2) = 6x + 6

Since the length of the actual rope is assumed to be 53 meters .The length of the first piece, second piece and third piece can be calculated as follows.

we add the length of the pieces to get the actual length of each piece. Therefore,

x + 2x + 2 + 6x + 6 = 53

collect like terms

9x + 8 = 53

9x = 53 - 8

9x = 45

x = 45/9

x = 5 meters

first piece = 5 m

second piece = 2(5) + 2 = 12 m

third piece = 3(2x + 2) = 6(5) + 6 = 36 m
