To hit the bulls eye the table would read
x=3.5 y=2
21. The ratio does add up to 50 so kinda confused
A circle is the collection of points ina plane that are the same distance from the CENTER (and not from the radius)
Then : False (answer B)
X / -2 = -4...multiply both sides by -2
x = -4 * -2
x = 8
===============
7a - 89 = 72
7a = 72 + 89
7a = 161
a = 161/7
a = 23 <==
===============
5x - 2 = 18
5x = 18 + 2
5x = 20
x = 20/5
x = 4 <==
