4(x-4)-3x=10 PLEASE ANSWER ASAP

The easiest way to solve this algebraic expression is to multiply the term 4 to its next term which is (x - 4) so as to get our resultant output and coefficient of x and a constant value. Solving the equation we'll get the value of x for the given expression which is given by,

Transferring (-16) to R.H.S. with 10,

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

4x and 6y

im not sure though
