Answer:
x > 6
Step-by-step explanation:

Prime numbers are not divisible by any number but themselves or 1.
A) 115 is divisible by 5, so it is not prime
B) 273 is divisible by 3 (you get 91), so it is not prime
C) 317 is prime! only divisible by itself or 1
D) 414 is divisible by 2, so it is not prime. Even numbers are never prime because they are divisible by 2!
Answer: 30
Step-by-step explanation:
40 + 8x = 280
-40 -40
8x = 240

X = 30
Answer:
Step-by-step explanation:
I can barely see enough to do 5 and 6. 7 the diagram is unclear and 9 I can't tell where the letters are. I suggest you darken the lines and make sure the letters for the unknowns are clear. Don't hold the paper: just as the picture was taken the image moved slightly. I don't know what to suggest.
Five
The ray defining a is pointing right at the five. That's my first assumption.
You need to find the interior angle connected to a.
Pentagon exterior angles
The total number of degrees for the exterior angles of a pentagon is 360
<em><u>Supplement of 140 degrees</u></em>
140 + x = 180 because the exterior and interior angles are supplementary
x = 180 - 140
x = 40
<em><u>Find a</u></em>
a + 40 + 60 + 84 + 68 = 360
a + 252 = 360
a = 360 - 252
a = 108
Six
This is really hard to read. Including b, there are three angles that are marked the same
Supplement to 68
180 - 68 = 112
Find b
112 + 43 + x + 89 + x +x = 360
244 + 3x = 360
3x = 116
x = 116/3
x = 38.67
Since b is marked as equal to 1 of the 3 exterior angles that are equal, b = 38.67
That is all I can read.
