Solve:
8x-7y=11 4x+2y=22

x=4 y=3

Step-by-step explanation:

Step-by-step explanation:

x2−y=2,2x−y=−1

4x+4y=1,6x−y=1

x+2y=4,x−y=−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

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho
