-3x + 3y = 24
x + 2y = 13

(x + 2y) - 2y = 13 - 2y
x = 13 - 2y

-3(13 - 2y) + 3y = 24
-39 + 6y + 3y = 24
9y - 39 = 24
(9y - 39) + 39 = 24 + 39
9y = 63
9y ÷ 9 = 63 <span>÷ 9
y = 7

x + 2y = 13
x + 2(7) = 13
x + 14 = 13
(x + 14) - 14 = 13 - 14
x = -1

When x = -1
y = 7


An easy way to check: 
-3x + 3y = 24
-3(-1) + 3(7) = 24
3 + 21 = 24
24 = 24

Since it is the same on both sides, our answers are correct. </span>

Another path in the community is 2.4 miles long. It has benches at 1/3 And 2/3 of the distance from beginning to end of the path
antoniya [11.8K]

Answer:

  the benches are 0.8 and 1.6 miles from the ends of the path

Step-by-step explanation:

The first bench is 1/3 of the path's length from the beginning of the path:

  (1/3)×(2.4 mi) = (2.4/3) mi = 0.8 mi

The second bench is 2/3 of the path's length from the beginning of the path:

  (2/3)×(2.4 mi) = (2.4×2/3) mi = 4.8/3 mi = 1.6 mi

The benches are 0.8 mi and 1.6 mi from the beginning of the path.

_____

Of course, 0.8 mi from the beginning is 2.4-0.8 = 1.6 mi from the end, and vice-versa.
