Answer: 1/2
Step-by-step explanation:
The 114 represents 80% of the total price before the sale. You would set up your equation as
Cost Price * 80% = Sale Price.
Sale Price = 114
80% = 80/100 = 0.8
Cost Price = 114/0.8
Cost Price = 142.50 which is the price before the deduction. You can confirm this by taking 20% of 142.50 and subtracting it form 142.50
20% * 142.50
20/100 * 142.50
2850/100
28.50
Now subtract 28.50 from 142.50
142.50 - 28.50 = 114 which is just what you might expect.
6x-y=3 this is the equation in standard form
Answer:
-170= -10m - 20
Step-by-step explanation:
-20 is the y intercept, so in the equation y=mx+b that would be the b. Because he is going down at 10 meters per minute, it means that the -10 would go into the x spot and the -170 is where he needs to get to. Hope this helped!
