-5(-3x+2)-4x-5=-48 looking for x

Step-by-step explanation:

-5(-3x + 2) - 4x - 5 = -48

-5*-3x + (-5) * 2 - 4x -5 = -48

15x - 10 - 4x - 5 = -48

15x - 4x - 10 - 5 = -48

11x - 15 = - 48

11x = -48 + 15

11x = -33

x = -33/11

x = -3

283.5km

Step-by-step explanation:

Given data

Speed= 63km/h

Time= 4.5hours

We know that speed= Distance/time

Make distance subject of the formula

DIstance= speed*time

Distance= 63*4.5

Distance= 283.5km

Hence the distance is 283.5km
