Since the discount is 20%, we know that $24 is 80% or 4/5 of the original price of the shoes. Divide the $24 by 20%, and you get $6. Add that to $24, and you get the original shoe price: $30. You can verify by Multiply 30 by 80%, which comes out to the discount price-$24.
A= 1/2 h ( sum of bases)

6550= 1/2h (115+85)
6550=1/2h (200)
6550= 100h
65.5= h
height is 65.5 cm

Answer:
The standard form is 
Step-by-step explanation:
The standard form of a linear equation can be written as

The given equation is

This equation is in the slope-intercept form.
To rewrite this in standard form, we must multiply through by the least common multiple which is 4.

We now add
to both sides of the equation to obtain,

This simplifies to

Hence the standard form is

The correct answer is A
Answer:
The answer should be D.
