Answer: (1,5)
Step-by-step explanation:
1. To solve this, use the midpoint formula:

2. Insert your values into the equation to get your answer

3. Simplify the formula
(1, 5)
4. The midpoint is (1, 5)
The equation would be d/r.
Hi my name is Greg and I like pizza
20.8478066 (or 20.85%)
you do 480.77 minus 380.54 and it comes out to 100.23 and then you do 100.23/480=x/100 (discount/original=percent/100) and you multiply 100.23 by 100 and it comes to 10023 and you do 10023 divided by 480.77 and it comes out to 20.8478066 or 20.85%
For this case we have the following system of equations:

We solve by the substitution method:
We substitute the first equation in the second equation:

We apply distributive property considering that 

We subtract 69 from both sides of the equation:

We divide by 8 on both sides of the equation:

We look for the value of the variable y:

Thus, the solution of the system is
