2x ">" -12 and 7x < 14. with negative numbers, the bigger the number the less it is. -12 < -6 because negative numbers work the opposite way that positive numbers do. I hope this helps you!!!!
#8) Subtract 350 from each side then divide each side by 25 to get (c-350)/25 = h.
Plug in 950 for c to get (950-350)/25 = h.
600/25 = h = 24 hours.
#9 is the same as number 8 just with one more variable. Subtract 2.25h from both sides and divide both sides by 1.75. Then plug in 18.25 for t and 5 for h. Then solve for d.
Answer:
Part A :
Robin : 50 divided by 4 = 12.5, Robin took 12.5 Weeks to get to 50 subscribers.
Dimitri : 17 divded by 7 = 2.4, Dimitri took 2.4 weeks to get to 7 subscribers.
Part B : In 7 weeks, Dimitri will have 66 subscribers, And in 4 weeks, Robin will have 66 subscribers. So after 7 weeks for Robin and 4 for Dimitri
Part C , They will have 66 subscribers. After 7 weeks Dimitri will have 66 subcribers, and after 4 weeks Robin will have 66 subscribers.
Explanation :
I have calculated out Robins and Dimitris subscribers counts with math.
Let the amount they both drive be x miles.
Then as the costs are the same
46 + 0.17x = 55 + 0.12x
0.05x = 55-46 = 9
x = 8/0.05 = 180 miles <------- answer to first part
This cos = 46 + 0.17*180 = $76.60 answer
