You multiply 0.6 by 5x and 10 and you get 3x+6=-24. you then subtract 6 from both sides of the equation and you get 3x=-30. after that you divide both sides by 3 and you get x=-10. so the answer is B!
V is a real number Because v is 1 which will tell you you came from 7 to 8 which was a 1 jump .
Well you have to multipy 4 x 11 and then add 4 x 10
