That's the only point within the circle, and it seems like the center. In these questions, just assuming it's perfectly in the center typically works.
75+37=112. 180-112=68. 68-7=61. 61/5=12.2. so x=12.2
Answer:
B is the correct answer accordingly to your question
Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
