Ineed asap hurry im begging for need it now im very on=8x-8, lm=7x+4, nm=x-5, and ol=3y-6, find the values of x and y for which lmno must be a parallelogram. the diagram is not drawn to scale.

x=12

y=11/3

Step-by-step explanation:

ON = 8x – 8

LM = 7x + 4

NM = x – 5

OL = 3y – 6

OL = NM

3y – 6 = x – 5

3y = x - 6 + 5

3y = x - 1

y = 1/3x - 1/3

ON = LM

8x – 8 = 7x + 4

x = 12

y = 1/3x - 1/3

y = 1/3(12) - 1/3

y = 4 - 1/3

y = 11/3

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

your answer would be 10x - 1
