Solve 4x - 5x + 2 = 3(2x - 4)
a. 2

b. 3

c. 4

d. 5

The true answer is A

Step-by-step explanation:

- x + 2 = 6x - 12

- x - 6x = - 12 - 2

- 7x = - 14

x = - 7 : - 14

X = 2

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

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
