One example, take the conversion fact that there are 5 miles for every 8 km.
Now if we want to work out how many kilometres in 6 miles, the conversion above is not going to help straight away.
We first need to find how many kilometres in ONE mile [which is the unit rate]
5 miles = 8 kilometres
1 mile = 8/5 kilometres
1 mile = 1.6 kilometres
Once we know the unit rate, we can then work out the number of kilometres for any number of miles.
For example:
6 miles = 6×1.6 = 9.6 kilometres
25.5 miles = 25.5 × 1.6 = 40.8 kilometres
Answer:
x = 14
Step-by-step explanation:
-1/5(x - 4) = -2
-1/5x + 4/5 = -2
-1/5x = -2 - 4/5
-1/5x = -10/5 - 4/5
-1/5x = - 14/5
x = -14/5 * - 5
x = 70/5
x = 14 <====

Step-by-step explanation:
The final cost of skateboard will be $83.10
Step-by-step explanation:
Given,
Cost of skateboard = $98
Coupon = 20% off
Amount of discount = 20% of cost of skateboard
Cost of skateboard after discount = Cost of skateboard - Amount of discount
Cost of skateboard after discount = 98 - 19.6 = $78.4
Sales tax = 6%
Sales tax amount = 6% of discounted price
Final cost of skateboard = Discounted price + Sales tax
Final cost of skateboard = 78.40+4.70 = $83.10
The final cost of skateboard will be $83.10
