Answer:
Discount Price is 16.54
The selling price is 20.22
Step-by-step explanation:
Make bottom number the same
it is 16
7/8 times 2/2=14/16
15/16+14/16+8/16=(15+14+8)/16=37/16=32/16+5/16=2+5/16=2 and 5/16 miles
Answer:
Equation: 
x = -10 or x = 7
x = 7 (width can't be negative)
x + 3 = 10
Step-by-step explanation:
Represent the width of the rectangle by x. "The length of a rectangle EXCEEDS the width by 3" means the length is 3 LONGER than the width, so the length is represented by the expression x + 3.
Area = (length)(width)
70 = (x + 3)x
Multiply out the right side.

Factor the left side.

Each binomial could equal 0, so

The negative solution does not make sense as the width of a rectangle.
x = 7, making the length, x + 3 = 10
