Step-by-step explanation:
Equation for Fast Internet is
45 + 50.45x
Equation for Quick Internet is
57.95x
To find when they cost the same , equate the 2 equations
45 + 50.45x = 57.95x ← required equation
Solve the equation by subtracting 50.45x from both sides
45 = 7.5x ( divide both sides by 7.5 )
6 = x
Both services would cost the same after 6 months
Answer:
12 football tickets for $72
Step-by-step explanation:
you do 72 divided by 12 and you get 6.
To solve this problem, you should know what is the not recovered waste for each item. To solve this, you should deduct the waste recovered from waste generated.
So for paper, the waste that is not recovered is 2.674 x 10^7.
While for glass, the not recovered waste is 0.840 x 10^7.
Lastly for plastics, the waste that is not recovered is 3.0554 x 10^7.
So by adding these three items, we can get now the total waste not recovered.
2.674 x 10^7 + 0.840 x 10^7 + 3.0554 x 10^7 = 6.5694 x 10^7.
