1) The simplest solution is C elimination.
2)
<span>7x + 5y = 19
–7x – 2y = –16
Add the equations:
3 y = 3
y = 1
7x + 5 = 19
7x = 14
x = 2
answer is A

Not sure i remember this but i think radius is like half of the diameter. it’s a line from the center, to a side of the circle. in this situation, line RO would be representing the radius.
answer: D, line RO
hope this helps :)
Answer:
Step-by-step explanation:
The protractor has inner and outer readings. The inner reading has graduations with intervals of 10 degrees and the outer reading also has graduations with intervals of 10 degree. We will use the outer graduations to take readings. On the outer reading, the shortest graduations is in intervals of 1 degree while the shorter graduation is in intervals of 5 degrees. Therefore,
a) angle AFB is 55 degrees
b) angle BFE is 180 - 55 = 125 degrees.
c) angle DFA is 126 degrees
d) angle BFD is 60 + 5 + 6 = 71 degrees.
e) angle CFD is 36 degrees
