Which choice is the solution for this system ? 2x − 5y = 14 x + 3 2 y = 5
VashaNatasha [74]

Answer:

The required solution is (5.75,-0.5). It can be written as (\frac{11}{4},-\frac{1}{2}).

Step-by-step explanation:

The given equations are

2x-5y=14                       .... (1)

x+\frac{3}{2}y=5            .... (2)

Multiply the equation (2) by 2.

2x+3y=10                     .... (3)

Subtract equation (1) from equation (3).

2x+3y-(2x-5y)=10-14

2x+3y-2x+5y=-4

8y=-4

y=-\frac{1}{2}=-0.5

Put this value in equation (1).

2x-5(-0.5)=14

2x+2.5=14

2x=11.5

x=5.75

Therefore the required solution is (5.75,-0.5). It can be written as (\frac{11}{4},-\frac{1}{2}).

Find the area of the kite please help and just don’t write down random answers
Zanzabum

Answer:

187.06 units²

Step-by-step explanation:

Area of kite:

½ × d1 × d2

½d1 = 18sin(30)

½d1 = 9

d1 = 18

d2 = 9/tan(60) + 18cos(30)

= 12sqrt(3)

Area = ½ × 18 × 12sqrt(3)

108sqrt(3) units²

187.0614872 units²
