I think the answer is D. 170 but if I’m wrong I’m totally srry
Answer:
x = 17, y = 9
or as an ordered pair, (17, 9).
The equations are consistent.
Step-by-step explanation:
2x - 3y = 7
x - 2y = -1 Multiply this equation by -2:
-2x + 4y = 2 Add this to the first equation:
y = 9.
Plug y = 9 into the second equation:
x - 2*9 = -1
x = -1 + 18 = 17.
Answer: The total length of nine pieces of chain is 121.248 yards.
Explanation:
Since we have given that
Length of each chain = 13 yards, 1 foot, 5 inches
As we know that

On Converting it into larger units, we get 13.472 yards
Now, Number of pieces of chain =9
Length of 9 pieces is given by

Hence, Nine pieces of chain are 121.248 yards long .
Process:
2/3x -7 = 17
17 + 7 = 24
2/3x = 24
2/3 = 24/x
24 ÷ 2 = 12
12 x 3 = 36
x = 36
Answer: X = 36
