13. How many solutions does this equation have: 8d-10=4(2d-6)?

1 answer:

6 0

13. 8d - 10 = 4(2d - 6)
8d - 10 = 8d - 12
8d - 8d = -12 + 10
0 = -2......incorrect....NO SOLUTIONS

14. 3.50c > = 500
c > = 500/3.50
c > = 142.857....she can sell (minimum) of 143

15. 14c - 10 = 20
14c = 20 + 10
14c = 30
c = 30/14 reduces to 15/7 (or 2 1/7)

16. c = 1.50g + 3

12.857 days

Step-by-step explanation:

Therefore;

180 – 6x = 0 + 8x

180 = 8x + 6x

180 = 14x

X = 12.857
