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

Then, we return the values where they belong.

u =  \frac{1}{x}  \\ 2 =  \frac{1}{x}  \\ x =  \frac{1}{2}  \\  \\ v =  \frac{1}{y}  \\ 3 =  \frac{1}{y}  \\ y =  \frac{1}{3}

Finally, we add:

\frac{1}{2}  +  \frac{1}{3}  =  \frac{3}{6}  +  \frac{2}{6}  =  \frac{5}{6}

6. Find the area shaded.
Rufina [12.5K]

Answer:

shaded area = total area - the two triangles areas

total area = 5*9 = 45 cm²

first tri area = 1/2 * h *b

= 0.5 * 5 * 2 = 5 cm²

second tri area = 0.5 * 6 * 5 = 15 cm²

shaded area = 45 - 15 - 5 = 25 cm²
