A 12 foot board is cut so that one piece is 5 times as long as the other. Find the length of each piece.
sveta [45]

Answer:

2 and 10

Step-by-step explanation:

Let x be length of the small piece and y the length of the big one.

● y = 5x

Since the big piece is 5 times longer than the short one.

The total length is 12 ft

● y + x = 12

● 5x + x = 12

● 6x = 12

Divide both sides by 6

● 6x/6 = 12/6

● x = 2

So the length of the two pieces are 2 ft and 10 ft (5×2)

I dont get it?? how do i set it up?? im so... confused?? can i get some helpm
snow_tiger [21]

Well, you need a diagram (see attached).

Since angle S = angle T then

9x -11 = 7x -3  ......  2x = 8 ........ x = 4

RS = RT = 4

There must be some more information that can't be seen
