Let x = original price in dollars
x is the original price
9% of this original price is equal to 0.09x
subtract: x - 0.09x = 0.91x
The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.
0.91x = 90
0.91x/0.91 = 90/0.91
x = 98.9010989
x = 98.90
So the original price is $<span>98.90</span>
Answer:
/the graph is a function.
First 42/78% to get 1% then multiply the number by 100% to get around 53 11/13
In order to find the area of a rectangle, the formula is L*W (Length multiplied by Width). Our goal is to find these two measurements, so we will take the following steps:
1) Plot the coordinates on a graph (I have attached a visual guide)
2) Using the Pythagorean Theorem, or the Distance formula we can find the length and width:

3) We will use these values in the Area formula for a rectangle (L*W)
4) After solving the Area formula with the values retrieved from the Distance Formula we find that
the area is roughly 30 units squared.
Answer:
x = 6.4 feet.
Step-by-step explanation:
If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).
Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,
And its sides are 9.8 feet, 10.9 feet, and x feet.
Therefore, 27.1 = ( 9.8 + 10.9 + x )
⇒ 27.1 = 20.7 + x
⇒ x = 6.4 feet (Answer)
