It says to solve for x but I don’t know how to do it

0 & 3

Step-by-step explanation:

(1/7)x² - (3/7)(x) = 0

Take (1/7)x common

(x/7)(x - 3) = 0

(x/7) = 0 when x = 0

x - 3 = 0 when x = 3

 x = {0, 3}

Step-by-step explanation:

First, clear the denominator.

Then move everything to one side so zero is on the other side (because it is a quadratic equation).  

Next, factor the quadratic equation.

Finally, solve each factor.

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

first one is a: renaming a fraction. second one is c: de-c
