Answer:
x=2 and y=-1
Step-by-step explanation:
set equations equal
X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
Hey You!
Let's solve this step-by-step:
9.99 * 20% = 1.998
9.99 - 1.998 = 7.992
7.992 * 6.75% = 0.53946
7.992 + 0.53946 = 8.53746
The total cost of his order is $8.53
One would be 4 over 6 or 5 over 6 hope I helped good luck
