Answer:
The answer is B. (2.5,-0.5).
Step-by-step explanation:
You would substitute the ordered pair into the first equation, making it
3(2.5)-(-0.5)=8. So the equation would become 7.5-(-0.5)=8, or 7.5+0.5=8. 8=8 is a true statement.
Step-by-step explanation:
circumference= 3.142*diameter
Diameter of main Street park is 30
Diameter of uptown park is 16
3.142*30=94.26
3.142*16=30.272
94.26-30.272=43.988
