Answer:

$\simeq 820 feet$

Step-by-step explanation:

He has asked me to move the finish line 0.25 km forward

Now,

we know that

1 km = 0.621371 mile

⇒ 0.25 km = $0.25 \times 0.621371$ mile

= $0.25 \times 0.621371 \times 1760 \times 3$ feet

(since 1760 yards = 1 mile and 3 feet = 1 yard)

= 820.20972 feet

$\simeq 820 feet$ . (Answer)

If 2/x+ 3/y =13 and 5/x- 4/y = -2, then x+y equals

creativ13 [48]

Answer:

$x + y = \frac{5}{6}$

Step-by-step explanation:

Let:

$u = \frac{1}{x} \\ v = \frac{1}{y}$

This allows us to manipulate the equations like we normally would.

$2u + 3v = 13 \\ 5u - 4v = - 2 \\ \\ + 8u + 12v = 52 \\ + 15u - 12v = - 6 \\ 23u = 46 \\ u = 2 \\ \\ 2(2) + 3v = 13 \\ 4 + 3v = 13 \\ 3v = 9 \\ v = 3$
