Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:
Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:
Next, use elimination to find the value of "x":
So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:
Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).

16/20 = 100/x
1.) 4/5 = 100/x
Simplify the fraction so it’s easier!
2.) 4x = 500
Cross multiply.
3.) x = 125
Divide both sides by 4 to keep it even.
Decrease in the price is = 320 - 240 = 80
So, percentage will be: 80/320 * 100 = 25%
So, option A is your answer.
Hope this helps!
Answer:
20, 24

16 + 4 = 20
20 + 4 = 24
The next 2 terms are 20, 24
