Answer:
A, C, F
Step-by-step explanation:
JK is proportional to PQ, so that would be 8/x. Then, JL is proportional to PR, which would be 10/5. So, the answer is: 8/x = 10/5
Then, C would also be correct as KL is proportional to QR, and JK is proportional to PQ.
Finally, F is correct as JK to KL is proportional to PQ to QR, as JK is proportional to PQ, and KL is proportional to QR.

Rule is 7 can only be divisible by 1 and no other number
The answer to this question would be: <span><span>between 8 and 10
In this question, the sports book get 9 votes but the ranges are made by twos which mean only even number will be placed on the track. The closest even number from 9 would be 8(1 number below) and 10(1 number above). So, the bar should be between 8 and 10</span></span>
OK so when you have absolute values it is very useful to think of abs(4 - v) as the distance between 4 and v.
Then you can write abs(4-v) < 5 as -5 < 4 - v < 5
This is because the distance between these two points must be in this range. Try writing out a real number line and giving random values to v. You will be able to see how this rule works!
Now that we have -5 < 4 - v < 5 we can solve it using basic algebra. We can solve it just like a normal equation but instead of doing an operation on "both sides" we have to do an operation on all three sides :D
-5 < 4 - v < 5
-5 -4 < 4 - v - 4 < 5 -4 add - 4 to all three sides
-9 <-v <1 simplify
-1 * -9 > -1 * -v > -1 * 1 multiply by -1 DONT FORGET TO SWITCH INEQUALITIES
9 > v > -1
-1 < v < 9
now just make sure you show in your number line what numbers v can be. <span>
