The sum of 6 consecutive integers is 519. What is the third number in this sequence?

86

Step-by-step explanation:

x+x+1+x+2+x+3+x+4+x+5 = 519

6x+15 = 519

6x = 504

x = 84

Third number = x+2 = 86

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
