1. 5/8 + 1/8 = 6/8 --> 3/4
3. - 1/4+ 3/4:
-0.25+0.75= 0.5 OR 1/2
5. 5/9 + 5/9 = 10/9 --> 1 whole 1/9
7. 3/10 + 1/10 = 4/10 --> 2/5
9. 7/15 + 4/15 = 11/15
And I simplified them too :P
Also this is ez, to me :PP
1: Its B
4: Its D
Sorry I don't know what how to explain it.

Answer:
21
Step-by-step explanation:
When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.
KL·KM = KJ·KC
Assuming the marks inside the circle apply only to the lengths inside the circle:
8(8+x+5) = 7(7+2x+1)
104 +8x = 56 +14x
48 = 6x
8 = x
Then the measure of MK is ...
MK = x+13 = 8+13
MK = 21
There are no real solutions.
if you subtract 20 from both sides, you get
x² = -16
You cannot find the square root of a negative number without using i, so there are no real number solutions.
