Drag each equation to show if it could be a correct first step to solving the equation 9(x+2)=90.

Answer is in the description

Step-by-step explanation:

1 goes into no

2 goes into yes

3 goes into no (I think)

4 goes into yes

5 goes into not enough (I think)

6 goes into yes

(Note that This is just what I would put)

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
