Ответ:
98 ft and 38 ft
Step-by-step explanation:
We know that the initial length of the piece is 136 feet
Then the piece is cut into two pieces.
Let's call x the length of the first piece of cable and call z the length of the second piece of cable.
So we know that
and
Now we substitute the second equation in the first one and solve for the variable z
Now we find the length x
Ответ:
50x + 30y = 550 . . . (1)
44x + 36y = 532 . . . (2)
(1) x 6 ⇒ 300x + 180y = 3,300 . . . (3)
(2) x 5 ⇒ 220x + 180y = 2,660 . . . (4)
(3) - (4) ⇒ 80x = 640
⇒ x = 640 / 80 = 8
From (1): 50(8) + 30y = 550
⇒ 30y = 550 - 400 = 150
⇒ y = 150 / 30 = 5
Therefore, the price of a chicken is $8 and the price of a duck is $5.
