Answer:
let x =the original price
then 116x/100=$39.32
116x=100×39.32
116x=3932
divide both sides by 116
116x/116=3932/116
x=33.89655
(2dp)
x=33.90
I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.

Answer:
32 units^2
Step-by-step explanation:
Finding the width and the length:
One side = √[(-1 - (-1)^2 + (5 - (-3))^2]
= √(0 + 64)
= 8.
The adjacent side = √(9-9)^2 + (-3-5)^2
= 8.
Perimeter - 4 *8 = 32 units^2.
Answer:
The answers are x=3;x= -2.Good luck!
Answer:
x^2 + y^2 = 100
Step-by-step explanation:
The general form of the equation of a circle is
(x-h)^2+(y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-0)^2+ (y-0)^2 = 10^2
x^2 + y^2 = 100
